Across
- 2. Energy added by an external source (usually a person or machine), by applying a force in the direction of motion
- 4. Actively pushing off air (Often generated by a helicopter with spinning blades or a rocket burning fuel)
- 7. Resistance due to moving through air
- 8. Pull by a rope, string or cable
- 11. Energy stored due to elevation
- 12. Energy transferred to a non-useful form (most often heat), caused by a force opposite the direction of motion
- 13. Energy stored in a stretched or compressed material
- 15. An object's change in velocity each second
Down
- 1. Surface resistance
- 3. Describes how far an object moved
- 5. Distance from the center (of a circle, curve or rotation)
- 6. Energy of motion
- 9. How fast an object is moving
- 10. Gravitational pull of the earth
- 14. How much stuff (protons, neutrons & electrons) an object is made of
