| Kinetic Energy | Anything that moves |
| Potential Energy | Stored energy - not moving yet |
| examples of potential energy | apple hanging on a tree |
| examples of kinetic energy | Football in the air |
| Friction | Resistance to motion caused by two objects moving against each other |
| Examples of more friction | Brakes pressing against a tire, tire rubbing against the street,sandpaper, any rough surface that causes things to slow down |
| Examples of less friction | wax paper, plastic wrap, aluminum foil, any smoother surface |
| Examples of Increasing Force | heavier objects need more force to be moved |
| Motion | described using Direction and Speed (Miles per Hour) |
| Force | The push and pull that causes a change in motion |
| Speed | a measure of the distance an object travels in a certain amount of time |
| Examples of increasing speed | graphs: |
| Mass | The more mass, the more force need to move it |
