Why is kinetic energy zero in uniform circular motion?
That makes sense. So, when we release a ball from rest on a curved track, how does its kinetic energy change as it moves down the track?
When we release a ball from rest on a curved track, the ball gains potential energy due to its position. As it moves down the track, this potential energy is converted to kinetic energy, causing the ball's velocity to increase. However, at any point on the track, the ball's kinetic energy is still zero in uniform circular motion.
