9. The SI unit of work or energy
10. The force of attraction by which terrestrial bodies tend to fall toward the center of the earth.
12. The capacity of a physical system to perform work
13. The branch of applied mathematics dealing with motion and forces producing motion
16. A type of energy that occurs due to the movement of electrons and protons in an oscillation pattern
18. Staying in one place without moving, or not changing
19. Energy of motion, observable as the movement of an object, particle, or set of particles

2. measure of how much a force acting on an object causes that object to rotate
4. Existing in nature and not made or caused by people
5. Strength or energy as an attribute of physical action or movement
