velocity | measurement of speed and direction of an object |
acceleration | the rate in an object's speed |
force | a push or pull that can change the motion of an object |
balanced forces | separate forces on an object that combined do not change the movement of the object |
unbalanced forces | forces on an object that cause change in the motion of the object |
net force | the sum of all the forces acting on an object |
at rest | the state of an object when it is not in motion |
direction | a straight path that an object can move along |
