Physics
Across
- 2. no resultant force or turning effect
- 5. used to determine gas pressure
- 7. the amount of matter per specific volume
- 8. the force of the earth that pulls us down to it
- 9. the force required to give a mass of 1kg a acceleration of 1m/s2
- 12. the force that is applied in a certain area
- 14. needs only magnitude to be described
- 15. the action of one body on a second body
Down
- 1. is caused by the gravitational acceleration acting on objects
- 3. mass x velocity
- 4. the place in a object where the whole weight is concentrated
- 6. the force needed to compress or decompress a spring a amount of distance
- 10. parachutists use this
- 11. needs both magnitude and direction to be described
- 13. acts when two body’s touch each other
