Across
- 2. Friction - Friction that prevents motion from starting.
- 6. - A push or pull on an object, measured in Newtons (N).
- 7. 3rd Law of Motion - For every action, there is an equal and opposite reaction.
- 8. - The speed of an object in a specific direction.
- 9. 1st Law of Motion - An object in motion stays in motion (and an object at rest stays at rest) unless acted on by an unbalanced force.
- 10. Friction - Friction when an object rolls over a surface.
- 11. - The amount of matter in an object, measured in kilograms.
- 12. Friction - Friction between two surfaces sliding past one another.
Down
- 1. - The force of gravity on an object (W = mx g).
- 3. - The rate at which velocity changes (speeding up, slowing down, or changing direction).
- 4. Resistance - A type of fluid friction that slows objects moving through air.
- 5. 2nd Law of Motion - Force equals mass times acceleration (F = ma)
