Physics
A pebble is thrown up. It goes to a height and then comes back on the ground. State the different changes in the form of energy during its motion.
Answer
On being thrown upwards, the kinetic energy of the pebble changes to potential energy.
Its kinetic energy is completely converted into potential energy when the pebble reaches its maximum height.
The potential energy is then converted into kinetic energy while coming down and the potential energy is completely converted to kinetic energy when the pebble reaches the ground.
