Across
- 4. the force or speed with which something moves (Mass x velocity)
- 7. The path of an object as it revolves around another object in space
- 10. Second Law A law that states a line running from the Sun to a planet sweeps out equal areas in equal times
- 11. collision A collision where kinetic energy is not conserved
- 12. The rate at which velocity changes
- 15. of momentum The amount of momentum stays constant assuming no outside force is applied
- 16. Field the region of space surrounding an object where other objects experience its gravity
- 17. the time required for one cycle, a complete motion that returns to its starting point
- 18. First Law The orbit of each planet around the Sun is an ellipse
Down
- 1. Force The sum of all forces acting on an object
- 2. A push or a pull
- 3. Law of Gravitation Objects gravities depend on mass and distance
- 5. collision A collision where momentum and kinetic energy are conserved
- 6. A elongated circle with two focal points
- 8. Third Law More distant planets orbit the sun at slower average speeds
- 9. A measurement of how elliptical an orbit is
- 13. Force an attractive force that acts between any two objects
- 14. fixed points at the centers of an ellipse
