Across
- 1. A force that opposes the relative motion of two surfaces in contact. It resists sliding motion.
- 3. A state where all the forces acting on an object are balanced, resulting in no net force and no acceleration.
- 7. A visual representation of all the forces acting on an object.
- 8. The force exerted on an object by gravity.
- 9. A quantity that has both magnitude and direction. Force, velocity, and acceleration are all vectors.
- 12. The point at which the mass of an object appears to be concentrated.
- 15. The rate of change of velocity. It is a measure of how quickly an object's speed or direction changes.
Down
- 2. The tendency of an object to resist changes in its motion.
- 4. The single force that represents the combined effect of all the forces acting on an object. It is equivalent to the net force.
- 5. A region in space where a force is present. For example, the gravitational field around the Earth.
- 6. The amount of matter in an object.
- 7. a push or a pull that can change an object's motion or shape.
- 10. three laws of motion and the law of universal gravitation. These laws describe the relationship between an object's motion and the forces that act upon it
- 11. A force exerted perpendicular to a surface by that surface on an object in contact with it.
- 13. The magnitude of an object's velocity. It is a scalar quantity (meaning it only has magnitude, not direction).
- 14. The sum of all forces acting on an object. It determines the object's acceleration and motion.
