Forces and Motion
Unit 3 Science
| Question | Answer |
|---|---|
| Location of an object | Position |
| Changes in velocity over time | Aceleration |
| The rate at which an object’s position is changing over time | Speed |
| Any change in position | Motion |
| Tendency of an object to resist a change in motion | Inertia |
| Measurement of an object’s speed and direction of motion | Velocity |
| A “frame” from which you can measure position or motion | Reference |
| Mass times velocity | Momentum |
| I am the word that scientists use for a push or a pull. What am I? | Force |
| I am the force that sometimes makes sliding difficult. What am I? | Friction |
| I am a force whose effect is offset by other forces so I won’t change your motion. What type of force am I? | Balanced |
| I am a force whose effect is not offset. So I change your motion in some way. What type of force am I? | Unbalanced |
| I am a force that slows down objects that are moving through the air. What am I? | Air resistance |
| I am a force that pushes an airplane forward. What am I? | Thrust |
| I am the tendency of an object in motion to stay in motion. What am I? | Inertia |
