Let's review the three laws of motion: Newton's first law of motion says that an object in motion will in motion and
an object at will stay at rest unless acted on by an unbalanced
An object will not change its motion unless a
acts on it.
An object that is not moving remains at rest until something pushes or pulls it.
An object that is moving remains moving until something pushes or pulls it.
All objects resist having their motion changed.
This tendency to resist a change in motion is called
The more mass an object has, the
its inertia
.
The second law of motion states that the force of an object is equal to its
times its acceleration
