**Force and Newton's Laws Vocabulary**

A push or a pull

the force that brings nearly everything to a stop.

The point in an object that moves as if all the objects mass were concentrated at that point.

Two or more forces exerted on an object. If effects cancel each other out, they do not cause a change in the object’s motion.

The effects of these forces don’t cancel each other. Anytime the forces acting on the object are _________, the net force is not zero and the motion of the object changes.

The Gravitational between you and the Earth. This would be different on another planet than on Earth.

An object will remain at rest or move with constant speed unless a net force is applied.

This connects force, acceleration, and mass; it explains that an object acted upon by a force will accelerate in the direction of the force; acceleration equals net force divided by mass.

Forces always act in equal but opposite pairs; for every action there is an equal ad opposite reaction
