Physics

1. the path taken through the air.
5. the science of describing the motion of an object.
8. a quantity that has magnitude and direction
9. one of the four fundamental forces of the universe; is exerted by anything that has mass on anything else that has mass.
12. Inertia-objects at rest tend to stay at rest and objects in motion tend to stay in motion
13. a push or pull.
16. the tendency of objects to resist changes in speed or direction of motion
18. a theorem that states that the square of the length of the hypotenuse of a right triangle equals the sum of the squares of the lengths of the other two sides.
19. quantity having only magnitude, not direction.
20. the more force in an object, the more it accelerates

2. the rate of change of velocity divided by time elapsed. The SI unit for acceleration is meters per second squared (m/s2).
3. the resistive force between an two objects.
4. the branch of science concerned with the nature and properties of matter and energy.
6. an object that is moving through the air.
7. a derived unit of measurement for force; one newton is equal to one kilogram times meters divided by seconds squared (kgm/s2).
10. a vector quantity that is equal to the addition of two or more vector components acting at the same point.
11. the amount or quantity.
14. the frictional force that air exerts on objects; also known as drag, FD.
15. a fundamental unit of measurement that is defined arbitrarily and not based on other combinations of units. Examples from the SI system include the meter, kilogram, liter, second, and kelvin.
17. every action has an equal and opposite reaction
