Down
- 1. a force that two surfaces exert on each other when they rub against each other
- 2. An object that is thrown
- 3. Forces that cause the velocity of an object to change
- 5. A fluid friction that acts on objects falling through air
- 6. Friction occurs when a solid objects moves through a fluid

- 12. The measure of the amount of matter in an object
- 14. movement that depends on both the mass and velocity of an object
- 15. Friction that acts on objects that are not moving
