Is circular motion possible at constant speed? Explain.

Is it possible to have constant speed when velocity changes?

A simple pendulum, suspended from the roof of a car. is Oscillating, Estimate the time period of pendulum when the car moves in a circular path at a constant speed?

In uniform circular motion of a particle

A particle is moving in a circular path of radius r with constant speed. Due to change in the direction of motion of the particle continously, the velocity of the particle is changing . But the kinetic energy of the particle remains the same. Explain why ?

If a particle moves in a circular path with constant speed, what should be the direction of its resultant acceleration?

Statement I: A car takes a turn of radius 20 m with constant velocity of 10 m cdot s^(-1) . Statement II: In circular motion, velocity can never be constant.

A stone of mass m, tied to a string of length 1 is rotating along a circular path with constant speed v. The torque on the stone is______.
