It should be In physics, there are a large number of physical quantities we include while performing calculations. To make it more convenient for users and easier to use and remember, we often use notations/symbols to represent these physical quantities. The work W done by a constant force of magnitude F on a point that moves a displacement s in a straight line in the direction of the force is the product W = F s . {\displaystyle W=Fs.} For example, if a force of 10 newtons ( F = 10 N ) acts along a point that travels 2 metres ( s = 2 m ), then W = Fs = (10 N) (2 m) = 20 J . The SI unit of power is the watt (W) or joule per second (J/s). Power is a scalar quantity, it has no direction. Horsepower is often used to describe the power delivered by a machine.

The SI unit of power is the watt (W) or joule per second (J/s). Power is a scalar quantity, it has no direction. Horsepower is often used to describe the power delivered by a machine. W = Fd The work is the product of the force and the displacement. In SI (international system) units, the unit of force is the Newton (N), and the unit of distance or displacement is the meter (m).

Under the 2019 redefinition of the SI base units, this sets 1 eV equal to the exact value … A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity. Any other quantity of that kind can be expressed as a multiple of the unit of measurement. For example, a length is a physical quantity. The metre is a unit of length that represents a definite predetermined length.

Another unit larger than watt is also used. It is called kilowatt (K.W.). Horsepower: Power of doing work of 746 Joules in 1 second is called 1 horse-power (H.P.). 1 H.P. = 746 J/s = 746 Watt. Practical unit of electricity: A practical unit of power for electricity is watt. Watt is also unit of power in the International system. Means, 1 watt

Velocity Velocity is the speed and direction of an object. Wavelength Meter (m) Work W Joule (J) Work is the amount of force outputted over some distance. Basic Units and Introduction to Natural Units 1 Basic units in particle physics In particle physics, the preferred length unit is the femtometer (or fermi), where 1 fm = 10−15 m. For example, the proton radius is ~1.0 fm. Cross sections are typically measured in “barns”, where 1b = 10−28 m2. These were a few widely used units along with their SI units. Apart from these units, there are certain additional units that are commonly seen in physics.
