Question

Find the angular velocity of particle
the origin
shown at
point P about the origin

​

Answer 1

Answer:

The angular velocity about P is ω

Angle swept about P in time t θ=ωt

Now, from properties of the circle, we know that angle subtended by an arc at the centre is double of the angle subtended anywhere on the circumference.

Hence angle subtended at O in time t is 2θ

Hence angular velocity=ω

o

=

t

2θ

=2ω
