| energy that is stored | potential energy |
| energy of a moving object | kinetic energy |
| An object in motion stays in motion. An object at rest stays at rest. | inertia |
| When a coaster rolls up a hill, it | transforms kinetic energy to gravitational potential energy. |
| When a coaster rolls down a hill, it | transforms gravitational potential energy to kinetic energy. |
| The starting hill on a roller coaster is always | the biggest. |
| An asteroid in motion would travel for ever | in a straight line. |
| A coaster ride with a lot of potential energy, | must have started at a high altitiude. |
| As a roller coaster car rolls down a hill, its potential energy is changed into | kinetic energy. |
| An object with a lot of kinetic energy | is fast. |
| A roller coaster car has the most speed | at the lowest elevations. |
| You would float out of the coaster seat | when the car rolls over the top of a steep hill. |
| If tracks were not banked, | cars would roll straight off the track. |
| As the speed of a car increases, | the momentum increases. |
| As momentum is tranferred away from a coaster car to the track, | the car slows down. |
| Wobbly roller coaster structures transfer away the car's momentum and as result, are | slower than solid steel roller coaster structures. |
| All objects seem weightless | when they fall. |
| This means "push" or "pull" | force |
| When objects speed up or slow down | acceleration |
