Across
- 2. when an object applies a force on another object, the second object applies a force of the same strentgh on the first object but the force is in the opposite direction
- 5. a measure of the change in velocity during a period of time
- 8. the difference between the initial or starting position and the final position
- 10. a force that one object applies to another object without touching it
- 11. an attractive force that exists between all objects that have mass
- 13. the starting point you choose to describe the location, or position, of an object
- 15. a push or a pull on one object by another object that is touching it
- 18. the forces two objects apply to each other
- 20. an object's distance and direction from a reference point
- 21. law that states that the acceleration of an object is equal to the net force exerted on the object divided by the object's mass
- 22. the force that pushes perpendicular to the object's surface
Down
- 1. the combination of all forces acting on an object
- 3. when colliding objects bounce off each other
- 4. the gravitational force exerted on an object
- 6. a reagion of space that has a physical quantity (such as force) at every point
- 7. an object at rest will stay at rest, and an object in motion will stay in motion unless a force acts on the object
- 9. a measure of the distance an object travels in a given amount of time
- 12. a quantity that has both magnitude and direction
- 14. a contact force that resists the sliding motion of two surfaces that are touching
- 16. the speed and direction of a moving object
- 17. a simple model to understand what will happen to an object due to a force
- 19. a push or a pull on an object
