Across
- 3. Law that states that an object at rest remains at rest, and an object in motion remains in motion at constant speed and in a straight line unless acted on by an unbalanced force.
- 4. The change in position of an object with respect to its surroundings in a given interval of time.
- 5. The unit mass is measured in.
- 9. Total force that is measured using the standard metric unit known as the Newton.
- 12. When unbalanced forces are acting on an object, there is a change in speed and/or ___________.
- 16. The rate of change of velocity.
- 17. The gravitational force with which the Earth attracts the masses towards its center.
- 19. An object's inertia is directly related to the object's _________.
- 20. Forces that are opposite in direction and equal in size.
Down
- 1. This is the unit for Force.
- 2. This force resists motion when the surface of one object comes in contact with the surface of another.
- 6. This law is also known as Newton's Second Law.
- 7. This is the vector form of speed.
- 8. The tendency of a body to resist a change in motion or rest.
- 10. The rate of change of position of an object in any direction.
- 11. Heavier objects require more _______ to move.
- 13. Type of relationship of the mass of an object upon the acceleration of the same object.
- 14. Law that states F = ma, or net force is equal to mass times acceleration.
- 15. Force that is applied in one direction that is greater than the force applied in the opposite direction.
- 18. A force that tells massive objects how to move. Always equal to 9.81 meters per second squared.
