Question | Answer |
---|---|
acceleration | occurs when an object speeds up,slows down or turns |
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 | states that the total momentum of objects that collide with each other is the same before and after the collision |
mass | amount of matter in an object |
momentum | measure of how difficult it is to stop a moving object,equals the the product of 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 |
instantaneous speed | the speed of an object at one instant of time |
displacement | the shortest distance from the initial to the final position of a point |
