Momentum is defined and the concepts of impulse, conservation of momentum, explosions, and collisions in one dimension are explained. Conservation of momentum states that the total momentum of two objects in a collision is constant. Explosions are discussed, noting that the vector sums of particles from an explosion will add up to the original object's internal impulse. Collisions are described as either elastic, where no kinetic energy is lost, or inelastic, where some kinetic energy converts to other forms of energy.

Physics: work, force and energy
The document discusses the concepts of force, energy, and work in physics including defining force as a push or pull, balanced and unbalanced forces, kinetic and potential energy, the conditions for work to be done as the product of force and displacement along the direction of force, and providing examples to illustrate these concepts.
αδμε εφαρμογη
As an object falls from rest under gravity, its gravitational potential energy is converted to kinetic energy. When the object hits the ground, its potential energy is zero and its kinetic energy is at a maximum. The work-energy principle states that the change in an object's kinetic energy equals the net work done on it. For impacts, the average impact force multiplied by the distance traveled during impact equals the change in kinetic energy from before to after the impact.

This document discusses forces and examples of forces used in everyday life. It defines a force as a push or pull that can change an object's motion. There are two types of forces: contact forces and forces that act over a distance. Examples of different forces given are gravitational, electric, magnetic, nuclear, and frictional forces. The document then provides examples of how forces are used in everyday activities like opening doors, pushing or pulling objects, kicking a ball, and applying brakes to stop a vehicle. It explores how forces change the motion of objects and their effects.

1. The law of conservation of energy states that energy cannot be created or destroyed, only changed from one form to another. The total energy in an isolated system remains constant.
2. The law of conservation of momentum states that the total momentum of an isolated system remains constant if no external forces act on it.
3. The law of conservation of angular momentum states that for a body or system of bodies with no external torque applied, the angular momentum about a fixed axis remains constant. Examples of this law include divers increasing their rotational speed during a spin and the evolution of stars from contracting gas clouds.
Work energy and power
Work is done when a body is displaced under the action of a force. Work (W) is equal to the product of force (F) and displacement (s). Work done against gravity is equal to mass (m) times gravitational acceleration (g) times height (h), or mgh. There are three types of work: positive work when displacement is in the direction of force, negative work when displacement is opposite the direction of force, and zero work when there is no displacement. Energy is the ability to do work and can exist in different forms such as mechanical, heat, and electrical energy. Mechanical energy includes kinetic energy, which is the energy of motion and equals 1/2mv^2, and potential energy
2.3 work energy and power
The document discusses various concepts in mechanics including work, energy, power, and collisions. It defines work as the product of the applied force and displacement in the direction of force. It provides examples of calculating work done by pushing/lifting objects and moving in a current. Kinetic energy is defined as 1/2mv^2 and gravitational potential energy as mgh. The principle of conservation of energy states that total energy in a closed system remains constant as it can only be transferred or transformed. Power is defined as the rate of doing work and is measured in Watts. Collisions conserve momentum and kinetic energy may or may not be conserved depending on whether the collision is elastic or inelastic.
Newton’S Third Law
Newton's Third Law states that for every action, there is an equal and opposite reaction. Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force back on the first object. Examples given include a hand pushing on a wall, which causes the wall to push back with an equal force, and a rocket pushing exhaust gases out, which causes the gases to push back on the rocket with an equal force. While the forces are equal, the effect of the forces depends on the masses of the objects, with lower mass objects experiencing greater acceleration from the same force.
Newton’s 3rd law of motion
Newton's third law of motion states that for every action, there is an equal and opposite reaction. Whenever one object exerts a force on another object, the second object exerts an equal and opposite force back on the first object. When a cannon fires, the cannonball exerts a forward force on the cannon while the cannon exerts a backward force of equal magnitude on the cannonball, causing the cannon to recoil. Although the cannon exerts an equal reaction force, it does not move back very far due to its greater mass compared to the cannonball.

Types of forces foldable
Forces can be categorized into different types:
1) Gravity (Fg) is the force of attraction between objects with mass, directing objects on Earth downward.
2) Friction (Ff) resists the sliding of objects in contact and opposes their motion.
3) Air resistance (Ff) is a type of friction that opposes the motion of objects through the air.
4) Normal force (Fn) supports objects in contact with stable surfaces.
Forces
A force is a push or pull between objects that has both size and direction. The net force on an object is the sum of all individual forces acting on it. Forces in the same direction are added, while forces in opposite directions are subtracted. Balanced forces produce no acceleration, while unbalanced forces cause acceleration that can be predicted using Newton's Second Law, which states that force equals mass times acceleration (F=ma).
Potential energy
Potential energy is stored energy that depends on an object's position or state of deformation. There are different types of potential energy including gravitational potential energy due to height above a gravitational body, and elastic potential energy stored in deformed springs and elastic objects. An example problem calculates the elastic potential energy stored in a spring attached to a hanging mass that has stretched the spring from its relaxed length. The work-energy theorem states that changes in kinetic and potential energy are related, and mechanical energy is the total of an object's kinetic and potential energies. An example shows using this to calculate the speed of a child sliding from rest down a frictionless slide given her initial height and mass.
Energy work and power
Energy exists in different forms including light, thermal, sound, electricity, gravitational potential, and kinetic. Kinetic energy is the energy of moving objects and can be converted to electricity through wind and water turbines. Gravitational potential energy is stored energy that exists from height and springs and can be converted to kinetic energy. The principle of conservation of energy states that energy cannot be created or destroyed, only converted from one form to another. Work is the transfer of energy done by a force over distance, and power is the rate of work done or energy converted per unit time.
Force, types, contact forces, non-contact forces
Force is defined as any push or pull that changes or tends to change the state of rest or uniform motion of an object. There are two types of forces: contact forces that require physical contact like muscular, frictional, and mechanical forces, and non-contact forces that act over a distance like magnetic, gravitational, and electrostatic forces.

Energy Transfer
The sun provides energy to Earth through various processes. Radiation transfers heat from the sun through space. When light from the sun hits objects, some of the energy is reflected back as reflection. Convection, conduction, and absorption are additional ways that the sun's energy is transferred and taken up by objects on Earth through the movement and absorption of heat.
Work, Energy and Power
ENERGY AND POWER
This ppt is from XI class CBSE board
Energy
A body which has the capacity to do work is said to possess energy.
For example , water in a reservoir is said to possesses energy as it could be used to drive a turbine lower down the valley. There are many forms of energy e.g. electrical, chemical heat, nuclear, mechanical etc.
The SI units are the same as those for work, Joules J.
In this module only purely mechanical energy will be considered. This may be of two kinds, potential and kinetic.
Power
Power is the rate at which work is done, or the rate at which energy is used transferred.
Equation 3.6
The SI unit for power is the watt W.
A power of 1W means that work is being done at the rate of 1J/s.
Larger units for power are the kilowatt kW (1kW = 1000 W = 103 W) and
the megawatt MW (1 MW = 1000000 W = 106 W).
If work is being done by a machine moving at speed v against a constant force, or resistance, F, then since work doe is force times distance, work done per second is Fv, which is the same as power.
Inertia 4
Inertia is the tendency of an object to resist changes in its motion. Objects at rest will stay at rest, and objects in motion will stay in motion, unless acted on by an unbalanced force. The greater the mass of an object, the greater its inertia, meaning more force is needed to change its motion. For example, it takes more force to start moving a heavy piano compared to a small toy piano due to the greater mass and inertia of the full-sized piano. If the net force on an object is zero, it will remain at rest or continue moving at a constant velocity.
Force,gravity,elastic
This document discusses different types of forces including friction, gravity, and elastic forces. It defines force as a push or pull and describes its magnitude and direction. Friction is explained as the force between two surfaces in contact. Gravity is defined as a force that pulls objects toward each other, with examples of its effects on weight and motion. Elastic forces like compression and tension are described as pushing or pulling matter based on its elastic properties.
Forces
In Grade 7, you described an object’s motion in terms of displacement, speed
or velocity, and acceleration. You performed activities wherein you interpreted or
created visual representations of the motion of objects such as tape charts and
motion graphs. The concepts were arrived at by studying examples of uniform
motion or objects moving in straight line at constant speed. Then you were also
introduced to non-uniform motion where the object covers unequal distances or
displacements at equal intervals of time. When a jeepney starts moving, it speeds
up. When a jeepney nears a stop sign, it slows down. The jeepney is covering
different displacements at equal time intervals and hence it is not moving at a
uniform velocity. In other words, the jeepney is accelerating.
Forces
This document defines key concepts related to forces. It explains that a force is a push or pull that can change an object's motion, having both magnitude and direction. Friction is defined as a force that opposes the motion of objects in contact. The net force is the combination of all forces acting on an object. Balanced forces cancel out, resulting in no change to motion, while unbalanced forces change an object's motion by starting, stopping, or altering its speed or direction. Inertia and Newton's Second Law are also introduced.
Force
The document defines and discusses the concepts of force and friction. It explains that a force always acts in a direction and lists examples of forces in nature. It defines weight as a force and introduces the Newton (N) as the unit of force. It distinguishes between balanced and unbalanced forces. It defines friction as a force that opposes motion and explains that friction occurs due to the roughness of surfaces in contact. It discusses kinetic and static friction and notes that friction can be both harmful and helpful.
Inertia 1
Inertia is the tendency of an object to remain at rest or in constant motion. The greater the mass of an object, the greater its inertia and resistance to changes in motion. According to the first law of motion, an object at rest stays at rest and an object in motion stays in motion with constant speed unless acted on by an unbalanced force.
Force
There are two main types of forces: contact forces, which require physical contact between objects, and non-contact forces, which act over a distance. The document goes on to define and describe several specific types of forces, including muscular force, magnetic force, electrostatic force, gravitational force, mechanical force, and frictional force. Each force is caused by a different interaction or phenomenon, such as muscle contraction, magnetic fields, charged particles, mass, physical contact between surfaces, or the movement of objects against each other.
Work, energy and power: for class IX
This slide describes the idea of work and work-done and various idea and principles about energy and its utilization. It defines the basic aspects of work and how it is related to each other
Force
The document discusses different types of forces. It explains that a force is something that changes or tends to change the shape, size, volume, state of rest, or motion of an object. It categorizes forces as either contact forces or non-contact forces. Contact forces require touching between objects, like muscular force, friction, and pushing/pulling. Non-contact forces act over a distance without touching, such as electrostatic force, gravitational force, and magnetic force between poles. The document provides examples of how these different forces work.
Undamped oscillation preasentation
Undamped oscillation occurs when there is no resistive force acting on an object that is vibrating. As the object oscillates, the energy is continuously transformed between kinetic and potential energy, but the total energy remains constant. In undamped vibration, the object will continue oscillating sinusoidally without losing amplitude. In reality, it is difficult to achieve true undamped vibration as even air provides some resistance.
04-16-08 - Conservation Of Momentum
This document discusses the conservation of momentum and different types of collisions. It defines elastic collisions as objects bouncing off each other, inelastic collisions as objects sticking together, and explosions as objects separating into fragments. It states that the total momentum of an isolated system remains constant before and after an event, using the equation that the initial momentum (m1vi + m2vi) must equal the final momentum (m1vf + m2vf). The document also provides links to simulation sites to examine elastic and inelastic collisions in one and two dimensions.
Notes 9.1
This document discusses momentum, impulse, and angular momentum. It begins by defining momentum and impulse, and how to calculate impulse from force and time. It then discusses how momentum and impulse are vectors and how their directions are important. Examples are given of calculating momentum and impulse in situations like hitting a baseball or stopping a moving vehicle. The document also introduces angular momentum and how torque is required to change angular velocity. Homework problems are assigned at the end to further understanding of these concepts.

Conservation of momentum
The document outlines the day's physics lesson plan which includes conducting an investigation, taking notes, and solving momentum problems. Students are instructed to gather materials and solve a warm-up problem. The lab activity will involve experiments and calculations on conservation of momentum using formulas to relate momentum before and after collisions between objects. Sample problems demonstrate applying the conservation of momentum principle to determine final velocities when objects stick together or move apart after collisions.
Momentum
The document discusses momentum, conservation of momentum, collisions, impulse, and friction. It defines momentum as mass times velocity and states that the total momentum before and after a collision remains the same if no external forces act, according to the conservation of momentum principle. It also distinguishes between elastic, inelastic, and completely inelastic collisions, and defines impulse as the change in momentum caused by a force over time. Static and kinetic friction are defined, with kinetic friction less than static friction. Examples and exercises demonstrate applications of these concepts.

The document discusses different types of collisions, including elastic collisions where no kinetic energy is lost, inelastic collisions where kinetic energy is lost, and the coefficient of restitution which measures the elasticity of collisions. Elastic collisions maintain the total kinetic energy before and after collision while inelastic collisions do not. The impulse-momentum theorem and conservation of linear momentum are also covered.
Physical Science - 3rd Law and Momentum
The document discusses Newton's Third Law and how it applies to examples of action-reaction force pairs such as a hammer and nail. It then covers the concepts of momentum, calculating momentum, conservation of momentum, and elastic versus inelastic collisions. Examples are provided to illustrate these physics principles around forces, momentum, and collisions.
Physics conservation of momentum
1) The document discusses the law of conservation of momentum, which states that the total momentum of an isolated system remains constant, regardless of interactions within the system.
2) Examples are given of how conservation of momentum applies, such as a gun recoiling after firing due to an equal and opposite reaction.
3) The total momentum of a system before a collision is always equal to the total momentum after collision according to the law of conservation of momentum.
Conservation of momentum - Physics
Newton's Cradle demonstrates the law of conservation of momentum through a series of balls. When one ball is pulled back and released, it strikes the next ball, transferring its momentum down the line and causing the last ball to move. This process repeats as the balls continue to exchange momentum. Rockets and jet engines also demonstrate conservation of momentum, as the high velocity exhaust ejected from the engines provides momentum that propels the engine in the opposite direction, allowing for flight. Collisions between objects also conserve total momentum, such as when squids eject water for propulsion or when players collide during a game.
Conservation of Momentum
The document provides instructions for a physics lab on conservation of momentum. Students will finish an investigation, take notes, and solve momentum problems. They will get materials ready and read background information. The lab involves measuring the momentum of colliding carts in groups and recording data. Students will analyze results using the law of conservation of momentum, which states that the total momentum before and after a collision remains the same if no external forces act. Sample problems demonstrate applying the law to calculate velocities after collisions.

The document discusses crumple zones in automobiles. Crumple zones are designed to absorb energy during a collision by crumpling instead of maintaining structural integrity. They help reduce injuries by lengthening the time of impact and decreasing acceleration forces on passengers. The experiment showed that adding more aluminum foil cylinders to simulate crumple zones increased stopping time and decreased maximum acceleration, with two cylinders performing best. Effective crumple zone materials include high density polymeric foam reinforced with fibers, surrounded by low density foam and mechanical ribs made of strong metals.
Newtons laws of motion
This document discusses Newton's laws of motion and concepts related to forces and motion, including inertia, momentum, friction, and more. Newton's first law states that an object remains at rest or in uniform motion unless acted on by an external force. The second law establishes the relationship between force, mass, and acceleration. The third law states that for every action there is an equal and opposite reaction. Friction is also examined, along with its causes and types. Coefficients of friction and angles of repose are defined.

This document summarizes key concepts about momentum and its conservation from a physics chapter. It defines momentum (p=mv) and impulse (FDt), and explains that momentum is a quantity representing an object's motion while force is what can hurt you. It discusses Newton's 3rd law in the context of momentum, how momentum is conserved in systems unless external forces act, and provides examples of conservation of momentum in collisions both one-dimensional and multi-dimensional. Key equations covered include impulse-momentum (FDt=Δp), conservation of momentum (p1+p2=p1'+p2'), and examples are worked through.
Force and laws of motion by Prabhat Gaurav IX
I hope you would like this ppt. This presentation mainly consist of the summary of the chapter Force and Laws of Motion in class IX NCERT pattern.
Law of momentum
This document provides examples and explanations of key physics concepts including:
- The law of momentum is used to calculate total momentum before and after collisions between objects of different masses moving at different velocities. Conservation of momentum is demonstrated.
- Graphs of position, velocity, and acceleration over time can show motion and changes in motion.
- Newton's second law relates force, mass, and acceleration. Examples show how to calculate any one of these values given the other two.
- Energy concepts like activation energy, work, and spring potential energy are defined and calculations are provided to determine these values in example scenarios.
Conservation Laws
This document discusses several laws of conservation in electromagnetism, including:
1) The continuity equation, which states that electric charge is locally conserved.
2) Poynting's theorem, which relates the work done by electromagnetic forces to the rate of change of electromagnetic field energy.
3) Maxwell's stress tensor, which describes the electromagnetic force density in a volume and relates it to momentum stored in electromagnetic fields.
Conservation Of Momentum
This document provides a presentation package on the topic of conservation of momentum for physics students. It includes:
1) An introduction defining momentum and the three types of collisions - elastic, inelastic, and partially elastic.
2) An explanation of the law of conservation of momentum, which states that the total momentum before and after a collision remains the same if no external forces act.
3) An example problem demonstrating how to use the law of conservation of momentum to calculate unknown velocities after a collision.
4) Additional examples and exercises for students to practice applying the law, along with a demonstration of why a gun recoils backwards after firing due to conservation of momentum.
Momentum - Chapter 9
The document discusses momentum and its conservation during collisions. It defines impulse as the product of an average force and the time interval over which it acts. The impulse-momentum theorem states that the impulse on an object equals its change in momentum. The conservation of momentum principle states that the total momentum of an isolated system remains constant, even after internal interactions and collisions within the system.
Momentum
Momentum is a quantity that expresses the motion of a body, equal to the product of its mass and velocity. The momentum of an object depends on its mass and velocity, with greater mass or velocity resulting in more momentum. The law of conservation of momentum states that in a closed system without external forces, the total momentum before and after an interaction will be the same. Examples include a person recoiling after firing a gun or moving backward when throwing an object off a skateboard. In collisions, the total momentum of the system is conserved and can be expressed mathematically as the sum of the momentum of the objects before equalling the sum after.

Momentum
- 3. Impulse
- 4. Conservation of Momentum The total momentum of two objects in a collision is constant.
- 5. Explosions In an explosion, the vector sums of all the particles involved will still add up to the internal impulse which had acted upon the original object. Example: A cannon will have a total momentum of zero, when the cannonball is released, then there will be equal momentum going forward and backwards thus making the total zero.
- 6. Collisions in One Dimension Elastic: A perfectly elastic collision is when no kinetic energy is lost. Inelastic: An inelastic collision is when part of the kinetic energy is converted into some other type of energy.
