Physics is a branch of science that studies matter and its motion as well as how it interacts with energy and forces. In other words, physics explains how the world around us works.

There are many branches of physics including electricity, astronomy, motion, waves, sound, and light. Physics studies the smallest elementary particles and atoms as well as the largest stars and the universe. Scientists who are experts in this field are called physicists. Physicists use the scientific method to test hypotheses and develop scientific laws. Some of the most famous scientists in history are considered physicists such as Isaac Newton and Albert Einstein.

Did you know that engineers use physics to help design airplanes, cars, buildings, and electronics such as computers and cell phones?
