| A | B |
|---|
| The motion of an object varies depending upon what? | the frame of reference of the observer |
| What is speed? | the distance a object moves in a certain amount of time |
| What is velocity? | the speed and direction of an object |
| An object traveling the same distance in each unit of time is said to be moving at this? | a constant speed |
| What type of curve does a constant speed have on a distance-time graph? | a straight line |
| What type of curve is produced when the object's speed varies with time on a distance-time graph? | not a straight line |
| How is an object's average speed calculated? | dividing the distance traveled by the total amount of time |
| What is acceleration? | change in velocity caused by speeding up, slowing down, or changing direction |
| What is an object moving in a circle an example of? | centripetal acceleration |
| What is energy? | the ability to do work and to cause change |
| What is potential energy? | energy of position or stored energy |
| What is kinetic energy? | energy of motion |
| What is the law of the conservation of energy? | states that energy is not created or destroyed |
