This document discusses vectors and equations of motion. It defines scalars as quantities that only have magnitude, and vectors as quantities that have both magnitude and direction. It provides examples of scalars and vectors, and explains how to calculate the resultant force or velocity when combining or subtracting forces/velocities acting in the same or opposite directions. It also lists four common equations of motion and defines the variables in each equation.
The Presentation is about the fundamental physical quantity Mass.
The presentation is motivated by my son back from school asked me "if weight is a force, and the unit of force is Newton, why aren't we buying potatoes in Newtons but in Kgs.
I didn't answer this question in my presentation. But, I facilitated students to find the answer themselves.
Torque, also called moment or moment of force, is the tendency of a force to rotate an object about an axis, fulcrum or pivot. Just as a force is a push or a pull, a torque can be thought of as a twist. In an electrical sense, torque makes the coil in a DC motor rotate due to the application of a force via the motor effect.
The document discusses gravitational potential energy and escape velocity. It defines gravitational potential energy as the amount of work needed to move an object from infinity to a specific point near a massive body, like Earth. The potential energy is always negative because the gravitational force is attractive. It also explains that escape velocity is the minimum speed an object needs to overcome gravitational potential energy and reach zero total energy to escape a planet or star's gravity. An example calculation determines Earth's escape velocity to be about 11,000 m/s.
This document defines various geographic terms including landforms like continents, oceans, bays, seas, straits, deltas, lakes, lagoons and rivers. It also defines geographic features such as capes, sounds, peninsulas, isthmus, plateaus, mesas, atolls, archipelagos, tundra and savannas. Additionally, it defines geographic measurement terms like latitude, longitude, tropics, equator and prime meridian.
This document discusses rotational motion and rotational inertia. It covers 6 topics: 1) rotational motion, 2) rotational inertia, 3) torque, 4) angular momentum, 5) rotational physics, and 6) conservation of angular momentum. The section on rotational inertia defines it as the property of an object to resist changes in its rotational state of motion. Rotational inertia depends on how mass is distributed about the axis of rotation, and objects with greater rotational inertia will take longer to start or stop rotating.
This document discusses Newton's laws of motion. It provides background on Newton, an overview of his three laws, and explanations of concepts like inertial mass, gravitational mass, weight, momentum, and energy. Newton's laws state that an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
The document discusses equations of motion using velocity-time graphs, including the relationships between displacement, average velocity, and the area under the graph. It provides examples of calculating time for one object to catch up to another using the kinematic equations and information about their initial velocities and accelerations. Practice problems are presented at the end to further illustrate applying the kinematic equations.

Newton's 3 Laws of Motion are summarized as follows:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
2) The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the direction of the net force.
3) For every action, there is an equal and opposite reaction.
Einstein's theories of relativity include the special and general theories. The special theory, published in 1905, deals with inertial frames of reference and the constancy of the speed of light. The general theory, published in 1915, extends these concepts to accelerated frames and explains gravity as a consequence of spacetime curvature. Key findings include spacetime being dynamic, light bending in gravity, and the equivalence of mass and energy. The Michelson-Morley experiment's null results disproved the ether hypothesis and supported Einstein's postulate that the speed of light is independent 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.
The document discusses the difference between mass and weight. Mass is the amount of matter in an object and does not change in different gravitational fields, while weight is the gravitational force exerted on an object's mass and does change in different fields due to differing gravitational strengths. It provides examples of how much an object would weigh on different planets and celestial bodies due to their different gravitational pulls, noting weight is calculated by multiplying mass by the local gravitational field strength.

The document discusses three equations of motion:
1) v=u + at, which gives the final velocity (v) of an object with initial velocity (u) under uniform acceleration (a) over time (t).
2) s=ut + 1/2at^2, which gives the distance (s) traveled by an object with initial velocity (u) and acceleration (a) over time (t).
3) v=u+2as, which can be obtained by eliminating time (t) from the first two equations and gives the final velocity (v) of an object that travels a distance (s) with initial velocity (u) and acceleration (a).
The document introduces the concept of linear momentum, which is defined as the product of an object's mass and velocity. Linear momentum depends on both the mass and speed of an object. The linear momentum of a system remains conserved as long as there are no external forces acting, according to the law of conservation of linear momentum. Collisions between objects also conserve linear momentum, with the total momentum before a collision equaling the total momentum after.
Motion can be described using concepts like position, displacement, distance, speed, velocity, and acceleration. Position refers to an object's location relative to a reference point, while displacement is the change in position. Distance is how far an object moves, while speed is the rate of change of distance over time. Velocity includes both speed and direction of motion. Acceleration describes the rate of change of velocity over time. Motion diagrams, graphs, and equations are used to quantitatively analyze and describe one-dimensional motion.
The document defines and discusses key concepts around mass, weight, density, and their relationships. It provides explanations and examples of how mass is different from weight and does not depend on location. It describes density as a ratio of mass to volume, and how density determines if objects will float or sink in liquids. Examples are given for calculating weight on Earth and other planets, as well as volume and density calculations using given values.
This document discusses static equilibrium and concepts related to determining if an object is in equilibrium. It defines static equilibrium as a state of balance where the forces acting on an object are balanced, causing it to remain at rest. It also discusses the center of gravity and how to locate it for different shapes, as well as the three states of equilibrium - stable, unstable, and neutral. Factors that determine an object's stability like mass, center of gravity location, and base of support are also covered.
The document discusses torque and its relationship to force and moment arm. Torque is defined as the tendency to produce rotational motion and is calculated as the product of a force and its moment arm. Several examples are provided to illustrate calculating torque based on given forces and moment arms. The importance of moment arm in producing torque is that torque depends on both the magnitude of force and its distance from the axis of rotation.
The document discusses linear momentum, impulse, and the conservation of momentum during collisions. It defines linear momentum as the product of an object's mass and velocity. It also states that the time rate of change of linear momentum is equal to the net force acting on an object. Impulse is defined as the force acting on an object times the change in momentum. The document outlines elastic collisions, in which both momentum and kinetic energy are conserved, and inelastic collisions, where kinetic energy is not conserved though momentum remains conserved. It provides examples of calculating momentum and velocities before and after both perfectly inelastic and elastic collisions.
The document discusses concepts related to equilibrium in physics including:
- Equilibrium as a condition where net forces are balanced out
- Statics as the study of structures in equilibrium under static forces
- Conditions for translational and rotational equilibrium as the sum of forces and sum of torques being equal to zero respectively
- Examples of calculating tensions in ropes and finding the center of gravity to solve equilibrium problems
Newton's three laws of motion are summarized as follows:
1) An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
2) The acceleration of an object as produced by a force is directly proportional to the force magnitude and inversely proportional to the mass of the object.
3) For every action, there is an equal and opposite reaction.
Today's physics lecture covered torque and rotational equilibrium. Key points included definitions of torque as the rotational effect of a force and rotational inertia. Examples were worked through to demonstrate torque, equilibrium conditions requiring the sum of forces and sum of torques to equal zero, and applications to problems involving objects in static equilibrium situations. An exam review and homework problems related to these concepts were also discussed.
This document discusses mass, weight, and density. It defines mass as a measure of the amount of substance in a body and explains that mass stays constant regardless of location, while weight depends on gravitational field strength and can vary in different locations. The document describes how gravitational field is a region where mass experiences gravitational force and how weight is calculated from mass and gravitational field strength. It provides equations for density and explains methods for measuring mass, weight, and density of liquids, regular solids, and irregular solids using balances and the displacement method.

Equilibrium and Equation of Equilibrium:2Drasel2211
This presentation discusses the concept of equilibrium in 2 dimensions. Equilibrium occurs when the net force and net torque on an object are both zero. This allows the object to remain at rest or in uniform motion. The key equations of equilibrium in 2D are: the sum of the horizontal forces equals 0 (ΣFx=0), the sum of the vertical forces equals 0 (ΣFy=0), and the sum of torques about the z-axis equals 0 (ΣMz=0). Examples are provided to demonstrate how to apply these equations to solve for unknown forces by drawing a free body diagram and setting up the appropriate equilibrium equations.
