1 WHAT IS PHYSICS?
... If you want to understand how an object (like a car, ball, person, or rocket) moves, you have to understand three things about what it means "to be moving." These three things "stick" to any object that moves, and are numbers that scientifically describe just how an object's motion is working. These ...
