Question
For a body moving along a circular path, show that:
Linear speed = Angular velocity X radius of the circle
Advertisements
Solution
Angular displacement θ = length of arc/ radius of circle
θ= I / r
I= θxr
divide above equation with t
l/t = θxr/ t
now l/t = v {linear speed)
θ/ r= w
So v = ωr.
