Newton's 3rd law of motion
This document discusses Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. It provides examples to illustrate this law, including a person sitting in a chair where their downward force on the chair is met with an equal upward force from the chair on the person. Other examples given include jumping into water from a boat, where the forward push on the water results in an equal backward force on the boat. The document also uses interactive questions to test understanding of Newton's Third Law, such as situations involving a firefly hitting a bus windshield and a rifle firing a bullet.
Newton third law of motion ppt
The document discusses Newton's Third Law of Motion, which states that for every action there is an equal and opposite reaction. It provides several examples to illustrate this law, including rockets propelling upwards as hot gases push down, cars moving forward as wheels push backwards on the road, a baseball hitting a bat causing the bat to push the ball in the opposite direction, and birds staying aloft as their wings push down on the air causing the air to push up with an equal force. Fish are also able to propel forward as their fins push water backwards with an opposing force. In each case, the size and direction of the action and reaction forces are equal and opposite.
Newton’s third law of motion
Newton's third law of motion states that for every action, there is an equal and opposite reaction. The document provides examples of this law, such as bumper cars pushing against each other with equal forces in opposite directions. It also explains that it can be difficult to identify the action-reaction pair when one object is much more massive than the other and does not noticeably move, such as the Earth when a person walks on it. The document asks the reader to think of additional examples of Newton's third law of motion.
Newton’s Third Law acloutier copyright 2011
Newton's Third Law 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 a force back that is equal in magnitude but opposite in direction. The key points are that forces always occur in action-reaction pairs between interacting objects and that these paired forces are equal in magnitude but opposite in direction.
Newton’s 3rd law of motion 2014 (1)
Newton's third law of motion states that for every action, there is an equal and opposite reaction. It explains that in all interactions, there is a pair of forces acting on two different objects. The document provides examples of this, including a person pushing on a wall, a bee flying, and a rocket launching. It notes that while the forces are equal, they do not cancel out or balance since they act on different objects that undergo motion.

Force and motion
The document discusses motion and forces, explaining concepts such as speed, velocity, balanced and unbalanced forces, friction, and Newton's Laws of Motion. It defines important terms like acceleration, inertia, and force, and explains how forces can cause changes in an object's velocity based on whether they are balanced or unbalanced. Examples are provided to illustrate concepts such as friction, gravity, and Newton's Laws.
Newton's laws of motion_564
Isaac Newton made several important contributions including developing calculus, proposing that light is composed of colors in the visible spectrum, inventing the reflecting telescope, and establishing his three laws of motion and the universal law of gravitation. Newton's laws of motion describe the relationship between an object's mass, its motion (including changes in motion), and the applied force. The first law deals with inertia, the second law defines the relationship between an object's acceleration, mass, and the applied force, and the third law states that for every action there is an equal and opposite reaction.
Newton’s laws application
The document discusses Newton's laws of motion, including the laws of inertia, acceleration, and interaction. It explains that Newton's third law states that for every action there is an equal and opposite reaction. Examples provided include a car exerting a force on the ground as it moves, which causes an equal reactive force from the ground pushing the car forward. When jumping on a trampoline, a downward force is exerted on the trampoline, with an equal upward reactive force propelling the person into the air.
Ppt Newtons Third Law
Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. When a force acts on an object, the object exerts a force of equal magnitude but opposite direction on the object applying the force. Examples given include a swimmer pushing off a wall, where the wall pushes back on the swimmer with an equal force, and a rocket, where the exhaust gases push backward on the rocket with an equal force, propelling it forward.
Gravity
1) Galileo Galilei proved in the late 1500s that all objects fall at the same rate due to gravity, regardless of their mass, contradicting Aristotle's belief that heavier objects fall faster.
2) Isaac Newton later explained that gravity is a force that exists between all objects due to their mass, and the strength of the gravitational force depends on the masses and distance between the objects.
3) The rate of acceleration due to gravity on Earth is 9.8 m/s2 for all objects, though air resistance can affect their actual falling speed depending on size and shape.
Gravity biophysics
This document discusses key concepts related to gravity including:
1) Gravity is defined as the force that attracts objects towards the center of Earth or other celestial bodies. Newton's law of gravitation states that gravitational force is directly proportional to the product of masses and inversely proportional to the square of the distance between objects.
2) Density is defined as mass per unit volume. Specific gravity is the ratio of a substance's density to that of water.
3) Archimedes' principle states that the buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object. This principle is applied in nursing for examples like hydrometers and urinometers.
Physics unit3
This document provides an overview of key concepts in mechanics, including:
1) Frames of reference and relative velocity - velocity measurements depend on the observer's frame of reference.
2) Forces cause changes in an object's motion. Forces are represented as vectors. Common forces include contact forces (from physical contact) and field forces like gravity (no contact required).
3) Newton's First Law of Motion (Law of Inertia) states 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.
Gravity and motion
The document discusses gravity and its effects on motion. It explains that gravity is a force of attraction between objects due to their masses. Gravity causes all objects to accelerate towards each other at 9.8 m/s^2. Air resistance can affect the motion of falling objects by slowing their acceleration. Isaac Newton formulated the law of universal gravitation, which states that gravitational force depends on the masses of objects and the distance between them.
Gravity2008
1) Galileo Galilei proved Aristotle wrong by showing that all objects fall at the same rate when dropped, regardless of their mass or material.
2) Gravity is a force that exists between all objects due to their mass. Isaac Newton later defined a law of universal gravitation to describe this force.
3) The acceleration due to gravity on Earth is 9.8 m/s2, causing all objects to accelerate at the same rate towards the ground in the absence of other forces like air resistance.
Law of interaction
According to Newton, whenever objects interact, they exert equal and opposite forces on each other. For example, when a bird flies, it pushes air downwards with its wings, and the air reacts by pushing the wings upwards, providing lift. Similarly, when a rocket launches, the hot gases push down on the rocket, while the rocket pushes up on the gases, providing thrust. Newton's third law of motion explains these interacting equal and opposite forces that produce motion.
Force & motion notes 2013
The document discusses key concepts related to motion and forces including gravity, acceleration, mass, friction, and air resistance. It defines gravity as a force of attraction between objects and explains that acceleration is affected by factors like air resistance, which opposes the motion of objects through air. The amount of air resistance depends on characteristics of the object like its size, shape, and velocity. The document also describes how as the speed of a falling object increases, air resistance increases until it balances the downward force of gravity, causing the object to stop accelerating and reach a constant velocity called terminal velocity.
Gravity
This document discusses key concepts of gravity including:
1) Gravity is a force that acts between any two masses, depending on their mass and distance. This is described by Newton's law of universal gravitation.
2) When the only force acting on an object is gravity, it is in free fall and accelerates at 9.8 m/s^2 near Earth's surface.
3) Air resistance opposes gravity and causes objects with greater surface areas to fall more slowly, until they reach terminal velocity where air resistance equals weight.
CM [012] Newton's 3rd Law
The basis of Newton's Third Law is also momentum which is also the foundation of classical mechanics. But what is momentum?
MOTION (force & motion) (Teach)
This document discusses force and motion, including Newton's three laws of motion. It explains that an object's motion changes when a force acts upon it. Newton's first law states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by an external force. Friction is introduced as a force that opposes motion. The document discusses the two main types of friction - static and sliding friction - and how friction depends on the surfaces in contact and an object's mass. Methods for reducing friction, such as lubrication and rolling motion, are also covered.
newtons laws of_motion
This document discusses Isaac Newton's three laws of motion and related concepts like inertia, balanced forces, unbalanced forces, and gravity. Newton's three laws are: 1) Objects at rest tend to stay at rest and objects in motion tend to stay in motion unless acted upon by an unbalanced force. 2) Force equals mass times acceleration. 3) For every action there is an equal and opposite reaction. The document provides examples and explanations of how these laws apply to real-world situations like a ball rolling to a stop due to friction or an object in space propelling itself back to a shuttle by throwing an object.
Newton laws
This document explains Isaac Newton's three laws of motion through examples and diagrams. Newton's First Law states that objects at rest stay at rest and objects in motion stay in motion unless acted upon by an unbalanced force. Friction and gravity are examples of forces that cause moving objects to eventually stop. Newton's Second Law states that force equals mass times acceleration (F=ma). Newton's Third Law says that for every action there is an equal and opposite reaction - when one object exerts a force on a second object, the second object exerts an equal force back on the first.
Free fall
The document discusses free fall and Galileo's experiments proving that all objects fall at the same rate regardless of their mass if air resistance is neglected. It notes that Galileo timed metal balls rolling down an inclined plane with a water clock to measure their speed of falling. The key equations for free fall acceleration due to gravity (g = -9.8 m/s^2) and relationships between displacement, time, initial velocity, and final velocity are also presented.
Gravity
The document discusses the key concepts of gravity including:
1) Gravity is a force that acts between any two masses and depends on their masses and the distance between them, as described by Newton's law of universal gravitation.
2) On Earth, gravity causes all objects to accelerate downward at 9.8 m/s^2 when in free fall with no other forces acting on them.
3) Air resistance counteracts gravity and causes objects of different sizes and shapes to fall at different rates, though they would fall at the same rate in a vacuum. Objects reach a terminal velocity when air resistance equals the downward force of gravity.
Gravity slideshare
Gravity is a force that pulls all objects downward at a rate of 9.81m/s2. Gravity acts on an object's mass, creating its weight. Factors like air resistance can affect how quickly different objects fall due to differences in mass and surface area interacting with the air.
Newton''s third law of motion
The document discusses Newton's Third Law of Motion, which states that for every action there is an equal and opposite reaction. It provides several examples to illustrate this law, including rockets propelling forward as hot gases escape out the bottom, cars moving forward as wheels push backwards on the road, a baseball hitting a bat to the left as the bat pushes the ball to the right, and birds staying aloft as their wings push air downwards causing an equal reaction force pushing the birds upwards. It also discusses how fish propel forward as their fins push water backwards.
Law of interaction
1) Newton's third law of motion states that for every action, there is an equal and opposite reaction.
2) Whenever one object exerts a force on a second object, the second object exerts an equal but opposite force back on the first object. These paired forces are called action-reaction force pairs.
3) Examples of action-reaction force pairs include a rocket exhaust pushing down on gases which push back up on the rocket with an equal force, and a car tire pushing down on the road surface while the road pushes back up on the tire.
Introduction to friction
This document discusses Newton's three laws of motion:
1) An object at rest stays at rest and an object in motion stays in motion 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 same direction as the net force, and inversely proportional to the mass of the object.
3) For every action, there is an equal and opposite reaction. The document provides several examples to illustrate each law, such as friction slowing objects in motion, forces needed to accelerate objects of different masses, and action-reaction force pairs in phenomena like flight.
Newtons Laws Of Motion
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.

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.
Newtons Laws Of Motion
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 unless acted upon by an unbalanced force (law of inertia).
2) The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object (F=ma).
3) For every action, there is an equal and opposite reaction.

App Naming Tip
For most of us, our name existed even before we did.
In anticipation of our arrival, our parents went through an ultra stressful process of narrowing down dozens of potential names until they chose the perfect one.
Luckily they did, because whatever your name is, it has followed you throughout your entire life; and in some cases, people may have heard of your name before they’ve ever met you.
When it comes to how to name an app, it’s of similar importance as naming a child. The name of your app will follow your brand forever, and in many cases, potential users will hear the name before they ever actually use your app.

Newtons laws and gravity
- 2. GRAVITY AND NEWTON’S LAWS OF MOTION By Prof . AJALA. J Head of Academics
- 3. Question???? Which object will land sooner if dropped at the same time, a tennis ball or a bowling ball?
- 4. Acceleration Due To Gravity Objects fall to the ground at the same rate because the acceleration due to gravity is the same for all objects. The mass of an object does not affect the rate at which it falls. Bowling ball and tennis ball
- 5. ACCELERATING AT A CONSTANT RATE All objects accelerate toward Earth at a rate of 9.8 m/s/s. WHAT DOES THIS MEAN? This means that for every second an object falls, the object’s downward velocity increases by 9.8 m/s.
- 6. Acceleration Due To Gravity Objects fall to the ground at the same rate because the acceleration due to gravity is the same for all objects. The mass of an object does not affect the rate at which it falls. All objects accelerate toward Earth at a rate of 9.8 m/s/s.
- 7. What happens when I drop a tennis ball and a piece of paper?? Is there something else acting on the paper to cause it to not fall like the tennis ball? What?
- 8. DOES AIR RESISTANCE AFFECT FALLING OBJECTS? Yes!! THE FORCE OF GRAVITY PULLS OBJECTS DOWNWARD AS THE FORCE OF AIR RESISTANCE PUSHES IT UPWARD. FREE FALL- when an object is being pulled down by gravity, but no other forces are acting on it. Does free fall occur with air resistance?
- 9. http://www.youtube.com/watch?v=5C5_ dOEyAfk Example of acceleration due to gravity
- 10. Gravity, Free Fall, and Air Resistance Gravity - the force that pulls objects toward one another. Free Fall – when only gravity is acting on an object. This is rare because of air resistance. All objects free fall at a rate of 9.8 m/s. A golf ball and basketball will hit the ground at the same time. Air Resistance – type of fluid friction which increases with the surface area of the object.
- 12. NEWTON’S FIRST LAW OF MOTION AKA: LAW OF INERTIA An object at rest remains at rest and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force. A golf ball on a tee. The man will remain in motion until a force stops his movement. Examples:
- 13. NEWTON’S FIRST LAW OF MOTION Also called: LAW OF INERTIA Inertia is the tendency of all objects to resist any change in motion.
- 15. NEWTON’S SECOND LAW OF MOTION The acceleration of an object depends on the mass of the object and amount of force applied. FORCE=MASS X ACCELERATION Or a=F/m How does Newton’s Second Law explain why the shuttle’s acceleration increases during takeoff?
- 17. • The greater mass or velocity an object has, the greater its inertia. • You can test this the next time you're at the grocery store! It takes a strong push to get a loaded shopping cart moving, but once it gathers speed it keeps going, even if you let go of the handle. When you stop a moving cart full of groceries, it takes much more force to stop it than an empty cart. Why? (it has more mass).
- 18. WHAT IS MOMENTUM? MOMENTUM is a property of a moving object that depends on the object’s mass and velocity. THE MORE MOMENTUM AN OBJECT HAS, THE HARDER IT IS TO STOP THE OBJECT OR CHANGE ITS DIRECTION. Momentum=mass x velocity
- 19. NEWTON’S THIRD LAW OF MOTION For every action there is an equal and opposite reaction. FORCES ALWAYS ACT IN PAIRS. The action force is the swimmer’s hand and feet pushing the water. The reaction force is the water pushing on the swimmer’s hands and feet.
- 20. • According to Newton, whenever objects A and B interact with each other, they exert forces upon each other. • When you sit in your chair, your body exerts a downward force on the chair and the chair exerts an upward force on your body.
- 21. • Flying gracefully through the air, birds depend on Newton’s third law of motion. As the birds push down on the air with their wings, the air pushes their wings up and gives them lift.
- 22. MORE EXAMPLES OF ACTION AND REACTION FORCE PAIRS The rabbit’s legs exert a force on Earth. Earth exerts an equal force on the rabbit’s legs, causing the rabbit to accelerate upward. The shuttle’s thrusters push the exhaust gases downward as the gases push the shuttle upward with an equal force.
- 24. Explain Newton’s First Law of Motion using this picture. A plane will not soar in the air unless it is pushed by the exhaust from its jet engines.
- 25. Newton’s Second Law of Motion - Which would you have to apply a greater force to stop and go? - Which would you rather buy gas for? - Which would you rather be driving in a head-on collision?
- 26. NEWTON’S THIRD LAW OF MOTION LIST and DESCRIBE the action and reaction forces in the following picture.
