Another word you might hear in everyday life which has a specific meaning in physics is "momentum".

An object's momentum is its mass multiplied by its velocity. Momentum is a vector so it has a magnitude and a direction, and the direction is the same as the velocity.

We'll also learn about impulse - a change in momentum caused by a force applied for a period of time.

After we understand momentum, we can learn about the law of conservation of momentum and how it applies to collisions in the next lesson.
