Physics is the study of matter and energy in space and time and how they are related to each other. Physicists assume (take as given) the existence of mass, length, time and electric charge and then define (give the meaning of) all other physical quantities in terms of these basic units. Mass, length, time, and electric charge are never defined but the standard units used to measure them are always defined.

Physics studies how things move, and the forces that make them move. For example, velocity and acceleration are used by physics to show how things move. Also, physicists study the forces of gravity, electricity, magnetism and the forces that hold stuff together.

Physics studies very large things, and very small things. For example, physics studies stars, planets and galaxies and other big pieces of matter. Physics also studies small pieces of matter, such as atoms and electrons.

Physics also studies sound, light and other waves. Physics studies energy, heat and radioactivity, and even space and time. Physics not only helps people understand how objects move, but how they change form, how they make noise, how hot or cold they will be, and what they are made of at the smallest level.

The branch of science concerned with the nature and properties of matter and energy

physics is basically the study ofunisverse...... every action which takes place on the universe is related to physics
