Term | Definition |
---|---|
Acceleration | equals the change in velocity divided by the time for the change to take place occurs when ann object speeds up slows down or turns |
Average Speed | equals the total distance traveled divided by the total time taken to travel the distance. |
Displacement | the distance you traveled to where you were. |
Inertia | tendency of an object to resist a change in it's motion |
Intantaneous Speed | the speed of an object at one instant of a time |
Law of conservation of momentum | states that the total momentum of an object that collide with each other is the same before and after the collision. |
Mass | amount of matter in an object. |
Momentum | a measure of how difficult it is to stop a moving object equals the product of the mass and velocity. |
Speed | equals the distance traveled divided by the time it takes to travel that distance. |
Velocity | speed and direction of a moving object. |
