Physics Terms

1. the force of attraction that moves or tends to move bodies towards the center of a celestial body, such as the earth or moon
5. the standard unit of measure for pressure
6. the number of times that a periodic function or vibration repeats itself in a specified time, often 1 second. It is usually measured in hertz
7. of any particle from its equilibrium
11. the standard unit of measure for energy and work
13. the maximum
14. the rate of increase of speed or change in velocity
15. the force per unit cross-sectional area when equal opposing forces act on a body
18. The amount of matter in an object
19. A quantity with magnitude but not direction
20. a resistance encountered when one body moves relative to another body with which it is in contact
21. the distance, measured in the direction of propagation, between two points of the same phase in consecutive cycles of a wave

2. a quantity that has both a magnitude and a direction
3. a unit for comparing two currents, voltages, or power levels
4. The mass divided by the volume of an object
8. the force over a given area
9. the product of a body's mass and its velocity
10. When two or more forces are balanced
12. A physical property of materials which return to their original shape after they are deformed
16. a force that tends to produce an elongation of a body or structure
17. a measure of the rate of motion of a body expressed as the rate of change of its position in a particular direction with time. It is measured in meters per second, miles per hour, etc
20. a dynamic influence that changes a body from a state of rest to one of motion or changes its rate of motion. The magnitude of the force is equal to the product of the mass of the body and its acceleration
22. the standard unit of measure for force
