In uniform circular motion, do the speed and angular velocity change?

  • Speed is distance covered by a body in unit time and it is constant in uniform circular motion.
  • Angular velocity is rate of change of angular displacement
  • In uniform circular motion,linear velocity have the direction along the tangent to the circle formed by the body in uniform circular motion, which is always changing. But the magnitude of linear velocity is constant. Angular velocity have direction perpendicular to the plane of uniform circular motion, which is given by right hand rule and its magnitude is constant because it covers equal angular displacement all time. 
  • Speed, kinetic energy, magnitude of linear momentum, angular momentum, radial acceleration are also constant.
