Motion and Force
7th grade Holt science
| Question | Answer |
|---|---|
| Distance divided by time | Speed |
| Speed and direction of an object | Velocity |
| An object that appears to stay in place | Reference Point |
| Combination of all forces on an object | Net force |
| A push or pull | Force |
| Kinetic | moving |
| Static | not moving |
| when the net force on an object is not 0 N, causes motion | unbalanced force |
| a force that opposes motion between 2 surfaces | friction |
| a decrease in velocity | deceleration |
| when the forces on an object produce a net force of 0 N, doesn't cause motion | balanced force |
| an objects change in position relative to a reference point | motion |
| rate at which velocity changes | acceleration |
| the unit for measuring force | Newton |
