Physical Science

2. mental or moral strength or power.
7. a body's relative mass or the quantity of matter contained by it, giving rise to a downward force; the heaviness of a person or thing.
9. a book forms part of a work or series.
10. the moving of something from its place or position.
13. the action or process of moving or being moved.
14. Force a force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
16. facts and statistics collected together for reference or analysis.
19. resistance air resistance describes the forces that are in opposition to the relative motion of an object as it passes through the air.
20. a vehicle's capacity to gain speed within a short time.
23. the rate at which someone or something is able to move or operate.
24. a substance made up of various types of particles that occupies physical space and has inertia.
25. the resistance that one surface or object encounters when moving over
26. an area of open land, especially one planted with crops or pasture, typically bounded by hedges or fences.
29. an open-meshed fabric twisted, knotted, or woven together at regular intervals
30. the force that attracts a body toward the center of the earth, or toward any other physical body having mass.

1. Acceleration the acceleration of a body traversing a circular path. Because velocity is a vector quantity
3. 2nd Newton's second law describes the affect of net force and mass upon the acceleration of an object.
4. of Conversation of Momentum in an isolated system the total momentum of two or more bodies acting upon each other remains constant unless an external force is applied.
5. Fall downward movement under the force of gravity only.
6. the speed of something in a given direction.
8. firm and stable in shape; not liquid or fluid.
11. level of quality or attainment.
12. a book forms part of a work or series.
15. is the quantity of motion of a moving body, measured as a product of its mass and velocity.
16. the degree of compactness of a substance.
17. plot or trace on a graph.
18. internationally known by the abbreviation SI is the modern form of the metric system and the world's most widely used .
21. Velocity the constant speed that a freely falling object eventually reaches when the resistance of the medium through which it is falling prevents further acceleration.
22. 1st every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force.
27. has the ability to do work.
28. 3rd for every action (force) in nature there is an equal and opposite reaction.
