what is relative velocity? give example
Asked by mehreennisar | 14th Feb, 2010, 06:17: PM
Velocity is always measured by a observer, therefore it's a relative quantity. For example, if someone says a train is moving with 60 km/hr. Then naturally the question is who measured it? and was the observer himself moving or stationary.
Relative velocity of A with respect to B = Velocity of A - Velocity of B.
For example, a bus overtakes a motorcycle and moving with speed of 60 km/hr, and the motorcyclist with a speed of 40 km/hr.
Then the relative velocity of the Bus with respect to motorcyclist = 60-40 = 20 km/hr.
