A body moving in a circle at constant speed has i. a velocity tangent to the circle ii. a constant kinetic energy iii. an acceleration directed towards the circumference of the circle. Which of the statements above are correct?
A body moving along a circular path with constant speed such that it traverses equal arc-length in equal intervals of time. Displacement, velocity and acceleration changes at each point on the trajectory. Hence, the speed is uniform and consequently the kinetic energy is also constant throughout.
