Across
- 2. the change in position of an object
- 9. the speed and direction of an object
- 11. any change in direction and/or speed, either faster or slower
- 12. Energy the energy an object has due to its motion
- 15. First Law an object in motion stays in motion, an object at rest stays at rest until acted upon by an external force
- 16. the measurement of how much matter is in an object
- 18. Energy the stored energy an object has becase of its position or state
Down
- 1. Machine a mechanical device with few or no moving parts that is used to simplify the motion of an object and reduce the needed force
- 3. Second Law the greater the mass of an object, the greater force needed to accelerate the object
- 4. Third Law when an object pushes on another object, the object being acted upon pushes back with equal force
- 5. a force of attraction between two masses
- 6. the rate at which an object travels in a certain amount of time
- 7. the resistance to motion when two objects rub against one another
- 8. when a force acts upon an object to cause it to move
- 10. of Conservation of Energy the amount of energy doesn't change; energy is not created or destroyed; it is only converted to other forms of energy
- 13. Speed the speed of an object at a specific instant in time
- 14. a push or pull that causes an object to have a change in movement or direction
- 17. how much ground has been covered during the movement of an object
