Physics Terms

1. the standard unit of measure for force
3. A quantity with magnitude but not direction
4. the force of attraction that moves or tends to move bodies towards the center of a celestial body, such as the earth or moon
7. the standard unit of measure for pressure
9. 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
10. 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
12. a unit for comparing two currents, voltages, or power levels
13. The mass divided by the volume of an object
16. the product of a body's mass and its velocity
18. the rate of increase of speed or change in velocity
19. the tendency of a body to preserve its state of rest or uniform motion unless acted upon by an external force
20. a quantity that has both a magnitude and a direction
21. The amount of matter in an object
23. the force over a given area

2. A physical property of materials which return to their original shape after they are deformed
5. the distance, measured in the direction of propagation, between two points of the same phase in consecutive cycles of a wave
6. a form of energy, which makes a body hot or cold
8. the maximum displacement of any particle from its equilibrium position
9. a resistance encountered when one body moves relative to another body with which it is in contact
11. a force that tends to produce an elongation of a body or structure
14. the standard unit of measure for energy and work
15. When two or more forces are balanced
17. a dynamic influence that changes a body from a state of rest to one of motion or changes its rate of motion
22. the force per unit cross-sectional area when equal opposing forces act on a body
