3. The rate of change of position of an object in any direction
7. Mirror a curved mirror where the reflective surface bulges out toward the light source.
9. Motion apparent daily motion of the heavens from east to west in which celestial objects seem to rise and set,
10. an event in which a planet's subsolar point passes through its Equator.
11. a change in the position of an object with reference to time.
13. measures the length between objects or points without regard for direction.
16. fall downward movement under the force of gravity only.
18. Energy the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
19. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.
20. Mirror a mirror that curves inward towards the reflecting surface.

1. the rate of change of velocity per unit of time.
2. Energy energy which a body possesses by virtue of being in motion
4. a vector whose length is the shortest distance from the initial to the final position of a point P undergoing motion.
5. reduction in speed or rate
6. Reaction a consequence of the action force. They have the same magnitude and nature. However, the differ in their direction
8. Motion the apparent yearly movement of the stars as observed from Earth as a direct effect of the Earth's revolution around the sun.
12. property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
14. the time when the Sun reaches its most northerly or southerly excursion relative to the celestial equator on the celestial sphere.
15. the strength and vitality required for sustained physical or mental activity
17. the speed of something in a given direction.
