physics terminology

2. the rate at which someone or something moves or operates or is able to move or operate.
5. the quality of being able to do a task successfully, without wasting time or energy
6. relating to or resulting from motion.
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.
10. strength or energy as an attribute of physical action or movement.
11. the speed of something in a given direction.
12. an increase or decrease in the magnitude of a property (e.g. temperature, pressure, or concentration) observed in passing from one point or moment to another.
13. a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
14. the principle by which the total value of a physical quantity or parameter (such as energy, mass, linear or angular momentum) remains constant in a system which is not subject to external influence.
16. the length of the space between two points.

1. a large body of matter with no definite shape.
3. the action of moving something from its place or position.
4. the quantity determining the energy of mass in a gravitational field or of charge in an electric field.
8. a state in which opposing forces or influences are balanced.
9. the rate at which an object changes its velocity, representing a vector quantity that includes both magnitude and direction
12. the force that attracts a body towards the centre of the earth, or towards any other physical body having mass.
15. the capacity to do work, cause motion, or produce change within a physical system
