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.
As you could probably guess, angular momentum is the rotational version of linear momentum. Instead of multiplying an object's mass and its velocity, we're going to multiply an object's rotational inertia and its angular 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.
