Consider the following statements and mark the statement as you answer which is correct in the context of kinetic energy and potential energy.

1. The kinetic energy of a molecule depends on the temperature while potential energy depends upon the position

2. The kinetic energy of an object is due to its position while potential energy is due to its velocity

3.  Both kinetic and potential energy of an object can be maximum at the same time

4. None of these

Potential energy that depends on height is called ________.

How can you define chemical energy? What is the relation between chemical energy and the potential energy or kinetic energy?
