When we study (4), or the study of matter and energy, we need to know two things to figure out how fast an object is going. First, we need to know how far the object traveled, or the (5). Second, we need to know how long it took the object to reach its destination, or the (6). By dividing the total distance by the total time, we can find the (7) of the object. This speed can be used to find the amount of (8) the ball has (the energy of motion).
