Question
An object is dropped from a certain height. Which of the following statements is correct about the object when it is at the highest position?
- It has minimum kinetic energy
- It has maximum kinetic energy.
- The kinetic energy is zero at this point.
- It has maximum potential energy.
Hint:
When an object is at some height then it possesses the potential energy due to its position. When the object is moving it possesses kinetic energy due to its motion.
The correct answer is: It has maximum potential energy.
An object is dropped from a certain height - It has maximum potential energy.
- Potential energy is the stored energy that depends upon the relative position of various parts of a system.
- P.E= mgh i.e. increase in potential energy when an object is taken to certain height 'h' and gravitational acceleration 'g'
