What is Physics?

Physics is the science of matter and its motion. It is an interesting science that deals with concepts like force, mass, energy, and charge. Its goal is to understand the natural world by finding quantitative physical laws for everything from the atoms to the planets, solar systems, and galaxies that occupy the cosmos. Physics is one of the oldest academic disciplines and due to its study of astronomy it may be the oldest of all. The basic laws in physics are universal Many of the technological inventions that we now see are the result of discoveries in physics. Physics Today is such a vast field that many subfields are almost separate sciences.

The early Greeks established the first quantitative physical laws like the Archimedes principle of levers and the buoyancy of bodies in the water. However, they were just bits and pieces of knowledge of physics because they were not organized experiments and documents. Physics started progressing properly only in the 17 th century when scientists like Galileo and later Issac Newton helped pioneer the use of mathematics as a fundamental tool in physics. This led to rapid advances in describing the motion of heavenly bodies, the laws of gravity, and the three laws of motion. Later, the laws of electricity, magnetism, and electromechanical waves were developed in the 1800s by Faraday and Maxwell. And soon many others contributed to our understanding of optics and thermodynamics.
