Physics Terms

2. The amount of matter in an object.
4. 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.
7. A resistance encountered when one body moves relative to another body with which it is in contact.
9. The force over a given area.
12. The maximum displacement of any particle from its equilibrium position.
16. A quantity that has both a magnitude and a direction.
17. The standard unit of measure for force.
18. When two or more forces are balanced.
21. The force of attraction that moves or tends to move bodies towards the center of a celestial body, such as the earth or moon.
22. The size of a measurement of a vector; scalar quantities that consist of a number and unit only, no direction, for example.
24. A force that tends to produce an elongation of a body or structure.
25. The mass divided by the volume of an object.

1. The rate of increase of speed or change in velocity.
3. A quantity with magnitude but not direction.
5. The tendency of a body to preserve its state of rest or uniform motion unless acted upon by an external force.
6. A unit for comparing two currents, voltages, or power levels.
7. A dynamic influence that changes a body from a state of rest to one of motion or changes its rate of motion.
8. The distance, measured in the direction of propagation, between two points of the same phase in consecutive cycles of a wave.
10. A physical property of materials which return to their original shape after they are deformed
11. A form of energy, which makes a body hot or cold.
13. The time required for one complete cycle of a wave.
14. 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.
15. The standard unit of measure for energy and work.
19. The product of a body's mass and its velocity
20. The standard unit of measure for pressure.
23. The force per unit cross-sectional area when equal opposing forces act on a body
