Power (physics)
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt (W), which is equal to one joule per second. Other units of power include ergs per second (erg/s), foot-pounds per minute, dBm, a logarithmic measure with reference to 1mW, calories per hour, BTU per hour (BTU/h), and tons of refrigeration.
Concept
In physics, power is the amount of energy transferred or converted per unit time. The SI unit of power is the watt, one joule per second. Power is also defined as the rate at which work is done or the amount of work done in a unit of time. Power is a scalar quantity.
Calculating power
Power can be calculated using the formula:
- P = W / t
where:
- P is power
- W is work done
- t is time
Power can also be calculated using the formula:
- P = F * v
where:
- P is power
- F is force
- v is velocity
Units of power
The SI unit of power is the watt (W), which is equal to one joule per second. Other units of power include ergs per second (erg/s), foot-pounds per minute, dBm, a logarithmic measure with reference to 1mW, calories per hour, BTU per hour (BTU/h), and tons of refrigeration.
