Motion & Forces
| Question | Answer |
|---|---|
| The straight line distance from starting to ending point with direction. | displacement |
| The background object used to determine if an object is in motion. | frame of reference |
| The change in position of an object over time. | motion |
| The length of the path taken from one place to another. | distance |
| The distance and object travels divided by the time it takes. | speed |
| Speed plus direction. | velocity |
| When two or more unequal forces push or pull on an object and cause a change in motion. | unbalanced forces |
| A push or a pull on an object. | force |
| When two or more forces push or pull with the same force and cause no change in motion. | balanced forces |
| The resulting force when two or more forces are acting on an object. | net force |
| The force acting the opposite direction of motion. | friction |
| The type of friction where it seems as if the object is stuck to the floor. | static friction |
| The type of friction shown when pushing a box across the floor. | sliding friction |
| The type of friction shown by a bicycle tire. | rolling friction |
