A few simple rules allow us to easily work out the dimensions of a derived quantity. Suppose that we have two quantities, \(X\) and \(Y\), both with dimensions.

WebApr 16, 2024 · A derived unit is a measurement unit for a derived quantity; for example, the metre per second, symbol m/s, and the centimetre per second, cm/s, are derived units of speed in SI. Coherent derived unit is a product of powers of base units with no other proportionality factor than one; e.g., metre per second is the coherent derived unit for ... WebIf velocity is defined as a distance quantity divided by a time quantity, then velocity is 25 meters/5.0 seconds. Dividing the numbers gives us 25/5.0 = 5.0, and dividing the units gives us meters/second, or m/s. The velocity is 5.0 m/s. Test Yourself.
