Question
A body is thrown vertically upwards. Its velocity keeps on decreasing. What happens to its kinetic energy as its velocity becomes zero?
Advertisements
Solution 1
Kinetic energy of the body changes to potential energy when it is thrown vertically upwards and its velocity becomes zero.
Solution 2
When a body is thrown vertically upwards against the force of gravity, its kinetic energy keeps on decreasing as its velocity decreases. At the maximum height, kinetic energy becomes zero, as the velocity of the body becomes zero at this moment. The kinetic energy of the body is completely transformed into potential energy at the maximum height.
