Physical Science

3. The rate of doing work Power = work/time
5. Distance traveled per unit time
6. Force, The force that supports an object against gravity, often called normal force.
8. The property of a system that it enables it to do work.
10. Cell, A device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent.
11. Pair, The action force and the reaction force that occur in an interaction.
13. The property by which objects resist changes in motion.
14. The quantity of space an object occupies
17. A device, such as a lever or pulley, that increases (or decreases) a force or simply changes the direction of a force.
19. Fake science that pretends to be real science.
20. energy, The energy that matter possesses due to its position: Gravitational PE= mgh
23. resistance, the force of friction acting on an object due to its motion in air.
24. Velocity, Terminal speed in a given direction (often downward)
25. A synthesis of a large body of information that encompasses well-tested and verified hypotheses about certain aspects of the natural world.
26. Force, The combination of all forces that act on an object.
27. The resistive force that opposes the motion or attempted motion of an object past another object with which it is in contact, or through a fluid.

1. A general hypothesis or statement about the relationship of natural quantities that has been tested over and over again and has not been contradicted; also known as a principle
2. A simple machine consisting of a rigid rod pivoted at a fixed point called the fulcrum.
4. An educated guess; a reasonable explanation of an observation or experimental result that is not fully accepted as factual until tested over and over again by experiment.
7. Inertia in motion given by the product of the mass of an object and its velocity.
9. The product of the force and the distance moved by the force: W= Fd
10. Fall, Motion under the influence of gravitational pull only.
12. simply stated, a push or a pull
13. The product of the force acting on an object and the time during which that force acts on that object.
15. an arrow that represents the magnitude and direction of a quantity
16. The force upon an object due to gravity. More specifically, the force with which a body presses against a supporting surface.
18. collision, A collision in which the colliding objects become distorted, generate heat and may even stick together.
21. The collective findings of humans about nature, and a process of gathering and organizing knowledge about nature.
22. A phenomenon about which competent observers who have made a series of observations are in agreement.
28. Speed, The speed at which the acceleration of a falling object terminates when air resistance balances its weight.
