How is energy conserved in particle interactions?

Energy is conserved in particle interactions through the principles of conservation of energy and momentum.

When particles interact, they exchange energy and momentum. However, the total energy and momentum of the system must remain constant before and after the interaction. This is known as the principle of conservation of energy and momentum.

In particle interactions, energy can be converted from one form to another. For example, kinetic energy can be converted into potential energy or into other forms of energy such as heat or light. However, the total energy of the system remains constant.

Additionally, momentum is conserved in particle interactions. Momentum is a vector quantity that describes the motion of an object. When particles interact, their momentum can be transferred to other particles, but the total momentum of the system remains constant.

Overall, energy conservation is a fundamental principle in particle interactions. It allows physicists to understand and predict the behavior of particles in various interactions, including collisions and decays.
