Across
- 2. Gravitational pull of the earth
- 3. Actively pushing off air (often generated by a helicopter with spinning blades or a rocket burning fuel)
- 5. The closeness of a measured value to a standard or known value
- 8. Distance from the center (of a circle, curve or rotation)
- 10. An object that is thrown
- 12. How fast an object is moving
- 14. The rate at which work is done
- 17. Refers to the closeness of two or more measurements to each other
- 18. Quantities that are fully described by a magnitude (or numerical value) alone
- 19. The force that pulls objects toward each other
- 20. Quantities that are fully described by both a magnitude and a direction
Down
- 1. Describes how far an object moved
- 4. How much stuff (protons, neutrons & electrons) an object is made of
- 6. Energy added by an external source (usually a person or machine), by applying a force in the direction of motion
- 7. Pull by a rope, string or cable
- 9. An object's change in velocity per second
- 11. The tendency of an object to resist any change in its motion
- 13. Energy transferred to a non-useful form (most often heat), caused by a force opposite the direction of motion
- 15. Resistance that one surface or object encounters when moving over another
- 16. Resistance due to moving through air
