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