,P1
energy The ability to do work
energy store a form of energy
kinetic energy energy which a body possesses by virtue of being in motion
gravitational potential energy energy an object possesses because of its position in a gravitational field
thermal energy the internal energy present in a system due to its temperature
elastic potential energy the energy stored in elastic materials as the result of their stretching or compressing
emit to give off or send out
absorb to take in
conservation of energy The principle that energy cannot be created or destroyed
closed system A system in which energy, but not matter, is exchanged with its surroundings.
pendulum A hanging mass that swings back and forth when pulled to one side and let go.
, work (joules, J) Force x Distance, the exertion of force overcoming resistance or
producing molecular change
joules the SI unit of work or energy, equal to the work done by a force of one newton when
its point of application moves one metre in the direction of action of the force
force (newtons, N) A push or a pull
Newtons the SI unit of force. It is equal to the force that would give a mass of one kilogram an
acceleration of one metre per second per second
kilograms the SI unit of mass, equivalent to the international standard kept at Sèvres near
Paris
mass (kilograms, kg) the quantity of matter which a body contains
weight (newtons, N) the force exerted on the mass of a body by a gravitational field.
metres (m) a measure of distance or displacement.
time (seconds, s) the indefinite continued progress of existence and events that occur in
apparently irreversible succession from the past through the present to the future.
unit standards for measurement of physical quantities that need clear definitions to be
useful
precision refers to the closeness of two or more measurements to each other
accuracy the degree of closeness of measurements of a quantity to that quantity's true value.
