Across
- 5. meters per second squared
- 9. an object in motion or rest will stay in motion or rest until some other force acts upon it
- 10. when all of the forces are acting on an object
- 14. the frictional force that is between the molecules of a liquid
- 15. a push or pull one object exerts on another
Down
- 1. action-reaction
- 2. forces that are in equal mass and in opposite direction
- 3. kg*meters per second squared
- 4. a force that pulls all objects towards the center of the Earth
- 6. the friction force that occurs when air pushes on an object moving in the opposite direction that the air is going
- 7. the force that makes it motion harder between two objects or materials that are in contact
- 8. friction, surface tension, air resistance, gravity, etc.
- 11. a measurement of the force that gravity pulls on an object
- 12. the tendency of an object to resist change in motion
- 13. the object will go in the direction that you push or pull it
