GAS- a substance possessing perfect molecular mobility and the HARMONIC MOTION- occurs when the force F acting on an
property of indefinite expansion, as opposed to a solid or liquid. object is directly proportional to the displacement x of the object,
but in the opposite direction.
GAUGE PRESSURE - is the pressure relative to atmospheric
pressure. Gauge pressure is positive for pressures above HARMONIC SEQUENCE- is a sequence such that each term
atmospheric pressure, and negative for pressures below it reciprocal form an arithmetic sequence (or sequence that has a

GRAVITATIONAL FORCE- is a force that attracts any two conditions, usually measured in joules per kelvin.

HEAT CONDUCTION- Thermal conduction, also called heat
GRAVITY- Is one of the four fundamental forces in the conduction, occurs within a body or between two bodies in
universe, alongside electromagnetism and the strong and weak contact without the involvement of mass flow and mixing.
nuclear forces.
HOOKE'S LAW- is an approximation of the response of elastic
(i.e., springlike) bodies. It states: the extension of a spring is in
direct proportion with the load applied to it. For instance, the
spring is pulled downwards with either no load, F p, or twice F p.
HYDRAULICS- the branch of physics having to do with the
mechanical properties of water and other liquids in motion
and with the application of these properties in engineering.
Origin of hydraulics.
