Gravitational energy is the potential energy held by an object because of its high position compared to a lower position. In other words, it is energy associated with gravity or gravitational force.
Explanation:
1. Gravitational force is an attractive force that comes into play when an object has mass. Hence all objects that have mass exert gravity on all other objects having mass.
2. Weak nuclear force is the force of attraction between an electron-antinutrino or positron-nutrino in a beta decay process, thus, this force is what makes sure that radioactive elements change into stable elements and elements having too high nuclear mass are not formed.
3. Electromagnetic force is force between any two charged particles such as electrons and protons, it can be either attractive (oppositely charged particles) or repulsive (similarly charged particles).
4. Strong nuclear force holds the nucleus together. It is the force between any two protons or neutrons once they come sufficiently close. Hence it is responsible for the stability of a nucleus.
