Velocity: tells both speed and direction of a car Acceleration: car has an acceleration if its velocity is changing in any way, whether in speed or direction or both. Acceleration of Gravity: is the acceleration of a falling object it is about 10 meters person second or more precise 9.8 m/s Momentum: Is the product of its mass and velocity Only way to change an object's momentum is to apply force to it. Angular momentum: Any object that is either spinning or moving along a curved path. Mass: the amount of matter in your body Weight: the force acting on your mass.

What Are Newtons three laws of motion?
