Motion/Force
3rd study stack for science.
Term | Definition |
---|---|
Acceleration | equals the change in velocity divide by the time for the change to take place; occurs when an object speeds up, slows down, or turns. |
Displacement | the act or process being displaced; state of being displaced |
Instantaneous Speed | the speed of an object at one instant of time |
Mass | amount of matter in an object |
Speed | equals the distance traveled divided by the time it takes to travel that distance |
Average Speed | equals the total distance traveled divided by the total time taken to travel the distance |
Inertia | tendency of an object to resist a change in its motion. |
Law of Conservation of Momentum | states that the total momentum of object collide with each other is the same before and after the collision |
Momentum | a measure of how difficult it is to stop a moving object; equals the product of mass and velocity |
Velocity | speed and direction of a moving object |
