4. the length of a path between two points
5. the movement of an object toward Earth solely because of gravity
9. the length of a straight line from the starting point to the ending point & the direction of movement; used to describe an object's position to a given point; tells the magnitude & direction
10. the rate at which velocity changes
11. the sum of 2 or more vectors
12. the velocity of the object changes by the same amount amount each second; a steady change in velocity
14. a quantity that has a magnitude and direction
