Across
- 3. The force when an object is moving over another
- 7. Contact force that is perpendicular to the surface that an object contains
- 9. pulling force
- 13. A force that requires contact to occur
- 16. A force that acts upon an object without physical contact
- 18. a force exerted by a compressed or stretched spring upon any object
- 20. the object’s motion does not change. If the object is at rest, it will stay at rest. If the object is moving, it will continue moving in the same direction with the same speed.
- 21. push or pull of an object
- 22. The force of gravity
- 23. The quantity of motion an object has
- 24. between electrically charged particles and their motion.
Down
- 1. an interaction between two objects that physically come into contact with each other.
- 2. More than one force can on an object at the same time, and the forces can act in the same or opposite directions
- 4. a scientist and mathematician who lived 1643 – 1727.
- 5. An upward force exerted by a fluid that opposes the weight of a fully immersed object.
- 6. An object at rest will remain at rest unless acted on by unbalanced forces. An object in motion continues in motion with the same speed and direction unless acted on by unbalanced forces.
- 8. a force that is applied onto another object
- 10. For every action there is an equal and opposite reaction.
- 11. A force between any two charged objects
- 12. An object accelerates when a force acts on an object with mass. The greater the mass of the object being accelerated, the more force needed to accelerate the object.
- 14. change in an object’s velocity
- 15. the tendency to resist change in motion
- 17. its motion will change. The object’s speed, position or direction will change. The change in an object’s motion depends on the net force acting on the object and the mass of the object.
- 19. The speed and direction of an object’s motion
- 23. the amount of matter in something
