Question

Which of the below-listed options is not an example of potential energy?

• A. Chemical energy
• B. Gravitational energy
• C. Mechanical energy
• D. Nuclear energy

Answer 1

The correct option is D

Nuclear energy

The explanation for the correct option:

In the case of option D,

1. Nuclear energy is a type of energy emitted by the nucleus of an atom.
2. Nuclear reactions, either fission or fusion, release nuclear energy.
3. Atoms combine to form a larger atom in nuclear fusion.
4. The Sun generates energy through the nuclear fusion
5. Nuclear power plants work on the principle of nuclear fission

The explanation for the incorrect options:

In the case of option A,

1. Chemical energy is the energy released by chemical substances when they encounter a chemical reaction and transform into another substance.
2. Chemical energy is a type of potential energy that exists in chemical bonds, subatomic particles, and atoms.

In the case of option B,

1. Gravitational energy is the potential energy a massive object has in relation to another massive object due to gravity.
2. It is the potential energy associated with the gravitational field, which is released when the objects fall towards each other.

In the case of option C,

1. Mechanical energy is defined as the sum of kinetic energy and potential energy.
2. The principle of mechanical energy conservation states that under certain conditions, the total mechanical energy of a system remains constant.

Hence, option D is the correct option
