Question : A body moving in a circular path with a constant speed has a:
Option 1: constant velocity
Option 2: constant acceleration
Option 3: constant kinetic energy
Option 4: constant displacement
Correct Answer: constant kinetic energy
Solution : The correct option is constant kinetic energy .
In circular motion at a constant speed, the velocity direction continually changes, leading to centripetal acceleration toward the circle's centre. Though speed remains constant, velocity, a vector involving magnitude and direction, varies. This continuous change in velocity direction causes the body to move in a circle, maintaining constant kinetic energy while experiencing centripetal acceleration.
