Acceleration

The change in Velocity divided by the time interval


Constant

A quantity that does not change in an equation
ex; g = 9.8m/s.s is the constant of gravity due to free fall. 

elliptical

moving in a round path.
ex; the planets move in an elliptical orbit 

energy

non material property of causing changes in matter


force

Agent that results in accelerating or deforming an object.


free fall

the falling of an object without any disturbance apart from earths gravity.


friction

a force that opposes motion


frictionless

without opposition of motion


impulse

product of force and the time interval at which it occurs


Independent Variable

A variable that is manipulated or change during an experiment.
