Here's why:
* Motion: Physics is all about understanding how things move, from the motion of planets to the movement of atoms.
* Force: Force is a fundamental concept in physics. It describes the interaction that causes a change in motion.
* Energy: Energy is the ability to do work. Physics explores the different forms of energy (like kinetic, potential, and thermal energy) and how they transform.
While other scientists might study aspects related to motion, force, and energy in their fields (like engineers, chemists, or biologists), physics is the core science dedicated to understanding these fundamental concepts.
