Question
A ball is thrown vertically upwards. Its velocity keeps on decreasing. What happens to its kinetic energy when it reaches the maximum height?
- Kinetic energy is double.
- Kinetic energy is zero.
- Kinetic energy is maximum at maximum height
- Kinetic energy is half of the initial value
Hint:
Kinetic energy is the energy which a body possesses by virtue of being in motion.
The correct answer is: Kinetic energy is zero.
A ball is thrown vertically upwards. Its velocity keeps on decreasing. when it reaches the maximum height Kinetic energy becomes zero.
- According to the law of conservation of energy the kinetic energy is converted into potential energy.
- So when it reaches the maximum height, Kinetic energy becomes zero.
