Force and Motion
Across
- 2. - when gravity is the only force acting on an object
- 4. law that states if no external force acts on a group of objects, their total momentum will not change
- 8. - the force exerted toward the center of a curved path
- 10. one of Newton's laws of motion that states an object at rest will stay at rest and an object in motion will stay in motion unless acted upon by a force
- 11. - the tendency of an object to resist any change in its motion
- 13. - a region of space that has a physical quantity (such as force) at every point
- 14. - the gravitational force exerted on an object
- 15. - the distance an object travels per unit of time
- 19. - a push or pull exerted on an object
- 20. - the rate of change of velocity
Down
- 1. - the distance and direction of an object’s change in position
- 3. - a change in an object's position relative to a reference point
- 5. - attractive force between two objects that depends on the masses of the objects and the distance between them
- 6. - the friction-like force that opposes the motion of objects that move through the air
- 7. - the speed of an object and the direction of its motion
- 9. - the maximum speed an object will reach when falling through a substance, such as air
- 10. - force that opposes the sliding motion between two touching surfaces
- 12. - sum of all the forces acting on an object
- 16. one of Newton's laws of motion that states force = mass x acceleration
- 17. - “p”, the product of an object's mass and velocity
- 18. one of Newton's laws of motion that states for every action, there is an equal and opposite reaction
