Across
- 1. distance divided by time
- 3. when two objects collide, the energy in one object does this to the other object
- 7. a physicist and mathematician, most known for his discoveries around gravity and the laws of motion
- 9. a metric unit of measurement to measure LONG distances
- 10. whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first object
- 12. an object at rest stays at rest, and an object that is in motion stays in motion
- 14. how much matter is in the object; does not change based on location
- 17. a force exerted between objects without the objects touching
- 19. a change in velocity over time
- 20. the measure of the force of gravity on an object; can change based on location
- 21. speed that is neither increasing nor decreasing
Down
- 2. as a roller coaster climbs upwards, the amount of this increases
- 4. a unit used to express force
- 5. moving energy
- 6. the speed of an object in any direction
- 8. the acceleration of an object depends on the mass of the object and the amount of force applied
- 11. a change in position over time
- 13. a push or a pull
- 14. a standard metric unit of measurement
- 15. the tendency of all objects to resist change in motion, so an object will not move until a force makes it move
- 16. a force that pulls objects toward each other due to their mass
- 18. is greater on a cement sidewalk than on an ice rink
- 22. the ability to do work
