physics. Gas laws, Laws that relate the pressure, volume, and temperature of a gas. Boyle's law—named for Robert Boyle—states that, at constant temperature, the pressure P of a gas varies inversely with its volume V, or PV = k, where k is a constant.
In conclusion, speed and velocity are kinematic quantities that have distinctly different definitions. Speed, being a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time ratio. Speed is ignorant of direction.
In physics, a wave is an oscillation accompanied by a transfer of energy. Frequency refers to the addition of time. ... A wave is a disturbance that transfers energy through matter or space. There are two main types of waves.
