As we know theta=arc length/radius =L/r L=r*theta velocity=displacement/time taken v=dl/dt (for a small movement of the particle)
from above …........... v=d(r*theta)/dt as r is constant it comes out =r(d*theta/dt) note: w(omega)=d*theta/dt …........ here w is angular velocity=angular displacement/time taken ….....so v=rw
