watt
That unit is called the watt - it's a unit of power.
Watt is the unit that measures one joule of work done in one second.
Power is the rate at which work is done or energy is transferred per unit of time. It is measured in units such as watts (W), where 1 watt is equivalent to 1 joule of work done per second.
1 joule per second = 1 watt
Work per unit time is power. It can be thought of as rate of doing work.
That unit is called the watt - it's a unit of power.
Watt is the unit that measures one joule of work done in one second.
Physicists believe it can be divided into approx 1.855*10^43 parts. Each part would then represent a Planck unit of time.
The definition of unit is that it DOESN'T represent anything. For example: two units of water could be two teaspoons or two gallons. The only thing unit-units are used for is comparing.
It is called the unit rate and gives the number of the first unit for each one in the second.
In science, speed is usually represented in meters/second.
It is power.
Power is the rate of use of energy in time. The unit of Energy is joule and the unit of Power is joule/second or Watt.
550 foot-pounds per second is a unit of power, specifically measuring the amount of energy transferred or converted per unit of time. It indicates the rate at which work is done or energy is used, with each pound of force applied over a distance of one foot per second.
The common unit of meters per second is used to measure speed or velocity. It represents the distance traveled in meters per each second of time.
A watt is the amount of work per second.
If you mean the pitch of a sound, that is related to its frequency. The SI unit is the Hertz.
