A pebble is thrown up .it goes to a height and then comes back on the ground .state the different changes in form of energy during its motion .

Dear Student, Please find below the solution of your asked query: When the pebble is thrown up with a velocity its kinetic energy is maximum at the start of its journey and then it goes on decreasing ,as the pebble moves upwards, its potential energy goes on increasing and then at the maximum height the potential energy is maximum, at this point the velocity becomes zero after that from its position in mid air it again starts to travel downwards under the action of gravity. At this point during its downward motion the potential energy slowly decreases and kinetic energy increases as the pebble moves downwards the kinetic energy is maximum just before the pebbel touches the ground and becomes zero when the pebbel touches the ground.
