Across
- 5. a measure of the amount of matter in an object
- 6. the resistance of an object to change in the speed or direction of its motion
- 9. the path that a body follows as it travels around another body in space.
- 10. the standard unit for measuring force in physics and engineering
- 12. a push or a pull; something that changes the motion of an object
- 13. the combination of all of the forces acting on an object
- 14. the acceleration directed toward the center of a circular path
- 15. a quantity that has both size and direction
- 17. the speed of an object in a particular direction
- 18. the distance traveled divided by the time interval during which the motion occurred.
- 20. a force of attraction between objects that is due to their masses.
Down
- 1. a mathematician and physicist who is best known for making the Laws of Motion.
- 2. the location of an object
- 3. the collection of eight planets and their moons in orbit around the sun, together with smaller bodies in the form of asteroids, meteoroids, and comets.,
- 4. the total length of the path traveled by an object,regardless of its direction.
- 7. the motion of a body when only the force of gravity is acting on the body.
- 8. the energy that an object has because of the position, shape, or condition of the object
- 11. a change in position over time
- 16. the rate of which velocity changes over time; an object accelerated if its speed, direction, or both change.
- 19. the ability to do work or to cause a change
