Physics is a branch of science that studies matter and its motion as well as how it interacts with energy and forces. Physics is a huge subject. There are many branches of physics including electricity, motion, waves, sound, and light. Scientists who are experts in physics 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.
Physics explains how the world around us works. Many of our modern technologies are based off of scientific discoveries made in the science of physics. Engineers use physics to help design airplanes, cars, buildings, and electronics such as computers and cell phones.
