Speed: tells us how far it will go in a certain amount of time. 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. Astronauts are weightless the entire time because they are in a constant state of free fall. How did Newton change out view of the universe? He showed that the same physical laws that operate on Earth also operate in space, making it possible for us to learn about the universe by studying physical laws on Earth. What Are Newtons three laws of motion?
