Why is the motion of a body moving with a constant speed around a circular path said to be accelerated ?

Question

 (i) Why is the motion of a body moving with a constant speed around a circular path said to be accelerated ?

(ii) Name the unit of physical quantity obtained by the formula 2k/v².

Where K: kinetic energy,v : linear velocity.

Answer 1

 (i) The motion of a body moving with a constant speed around a circular path is accelerated due to the continuous change in its direction at each point of circular path.

Hence, the physical quantity obtained is mass and its unit is kilogram (kg).
