Its scope of study encompasses not only the behavior of objects under the action of forces but also gravitational, electromagnetic, and nuclear force fields.
Physics is the natural science of matter, involving the study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, with its main goal being to understand how the universe behaves.
By the end you should have a nice understanding of introductory physics and the mathematical tools physicists use to describe and explain the universe. But no summary can describe all the interesting and powerful aspects of physics. The best way to find out is to jump in and see for yourself.

- Can Newton’s 1st and 2nd law of motion both be active at the same time?Sure. Newton's first law states that an object at rest or moving with a constant velocity will stay at rest or stay moving with a constant velocity...
- why is there no gravity in space? and why do we have gravity?There actually is gravity in space: the whole reason the Earth orbits around the sun is because the sun is a 'heavy' object that makes an impressio...
Feb 10, 2019 · Physics is the scientific study of matter and energy and how they interact with each other. This energy can take the form of motion, light, electricity, radiation, gravity — just about anything, honestly.
