the distance an object travels per unit of time | speed |
the total distance traveled divided by the total time of travel | average speed |
the speed at a given point of time | instantaneous speed |
includes the speed of an object and the direction of its motion | velocity |
the rate of change of velocity | acceleration |
a push or pull | force |
when two or more forces act on an object at the same time the forces then combine | net force |
forces on an object that are equal in size and opposite in direction | balanced force |
the tendency of an object to resist any change in its motion | inertia |
