Have you ever wondered how the universe works?

If so, you're not alone. Physics is the study of the natural world, and it offers an insight into how the universe works on a fundamental level. Physics is divided into three main branches: classical physics, quantum physics, and nuclear physics. Classical physics is the most basic form of physics and it is based on the principles of Newtonian mechanics. This theory states that objects in a system remain in equilibrium, and that the forces between them are constant.

Quantum physics is based on the principle of the quantum mechanics.

This theory states that the behavior of matter can be described by waves and particles, and that the energy of these waves and particles can be in different forms. Nuclear physics is the study of the nucleus, the center of the atom. This branch of physics is important because it provides insight into the origins of the elements in the universe.
