Across
- 4. The resistance that one surface or object encounters when moving over another.
- 7. When two forces acting on an object are not equal, causing a change in the object's motion.
- 12. When two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.
- 14. The force that attracts a body toward the center of the earth, or toward any other physical body having mass.
Down
- 1. The overall force acting on an object when all the individual forces acting on it are combined.
- 2. A push or pull on an object that can change its motion.
- 3. The change in an object's position over time.
- 5. The tendency of an object to resist changes in its state of motion.
- 6. A measure of the amount of matter in an object, typically measured in kilograms or grams.
- 8. The rate of change of velocity of an object with respect to time.
- 9. The distance an object travels per unit of time, without regard to direction.
- 10. The resistance force caused by the motion of a body through a fluid, such as air or water.
- 11. The speed of something in a given direction.
- 13. The force exerted on a body by gravity, calculated as the mass of the object times the gravitational acceleration (W = mg).
