rate
of change of velocity, which occurs if an object speeds up, changes
direction, or
slows down a. | force | c. | average
speed | b. | acceleration | d. | velocity | | | | |
|
|
|
2.
|
describes the speed and direction of a moving object a. | velocity | c. | distance | b. | inertia | d. | acceleration | | | | |
|
|
|
3.
|
total
distance an object travels divided by the total time it takes to travel that
distance a. | distance | c. | average
speed | b. | speed | d. | displacement | | | | |
|
|
|
4.

speed | c. | acceleration | b. | average speed | d. | speed | | | | |
|
|
|
5.

on a body that are equal in size and opposite in direction and do not change the motion of the
body a. | balanced
force | c. | net

point a. | displacement | c. | instantaneous
speed | b. | inertia | d. | average speed | | | | |
|
|
|
8.
|
speed
of an object at a given point in time, which is constant for an
object moving
with constant speed and is different at each point in time for an object that is slowing down or
speeding up a. | speed | c. | average
speed | b. | instantaneous speed | d. | velocity | | | | |
