It doesn’t matter which force we call action and which force we call reaction.

Action and reaction forces are not equal in strength.

If you drop a pencil, the pencil pulls Earth upward with a much smaller force than that with which Earth pulls the pencil downward.

A rocket is propelled by the impact of exhaust gases against the atmosphere.

The upward force that causes helicopters, birds, and airplanes to fly is called lift.

When a cannonball is fired from a cannon, the force the cannon exerts on the cannonball is exactly equal and opposite to the force the cannonball exerts on the cannon.

The trillion and trillions of interatomic forces that hold a baseball together do play a role accelerating the baseball.

If the action and reaction forces are internal to a system, then the forces cancel and the system does not accelerate.

Whenever one object exerts a force on a second object, the second object always exerts the same amount of force back on the first object.

A rocketship is pushed forward by gases that are forces out the back of the rocket.

To make a cart move forward, a horse must pull harder on the cart than the cart pulls on the horse.

If a bicycle and a parked car have a head-on collision, the force of the impact is greater on the bicycle.

The earth and moon pull on each other with equal amounts of force.

A force is always part of a(n) ____________ that involves another force.

How is this an example of Newton’s Third law?

If the person is pushing backwards with the paddle, why do they move forward?

When the person pushes on the brick wall, and the wall pushes back, why does the person move and not the wall?

You can't exert a force on anything unless it also exert a force on you

book exert on the desk?
