Question

Write the formula to calculate the speed of a body moving along a circular path of radius r whe it has completed N revolutions in time t

Open in App

Solution

The circular velocity formula is expressed as,

v = 2 πr / t

Where in,

r denotes the radius of the circular orbit

t is time period.

N = 1/ t
N is no. revolutions in t

So the above formula can be written as,

V = 2πrN
