Motion Vocabulary
A measure of how hard it is to stop an object momentum
Distance traveled divided by the time it takes to travel the distance Speed
Amount of matter in an object Mass
Change in velocity divided by the time it takes for the change to occur Accleration
Speed AND direction of a moving object Velocity
Speed of an object at one instant of time Instantaneous Speed
Total distance divided by the time taken Average Speed
Tendency of an object to resist change in its motion Inertia
What unit is used to measure speed? m/s
Formula for speed S=distance time
When objects collide the total initial momentum and final momentum are equal Law of Conservation of Momentum
Slowing down can also be called this Negative acceleration
SI unit for mass Kilogram (kg)
SI unit for accleration m/s2
