How is the term 'matter' defined in physics?

Answer 1

Matter is anything that is affected by gravity and possesses volume. Ordinary matter consists of atoms and elementary particles such as protons, neutrons, and electrons. A body is a single coherent piece of matter which is a collection of all these atoms and subatomic particles. Mass or inertia determines how much a body is affected by gravity. Volume determines how much space a body occupies. Matter can be converted into energy as shown by Einstein's equation, E=mc^2. Matter generally exists in four fundamental states as a solid, liquid, gas, and plasma.

Answer 2

In physics, matter is defined as anything that has mass and occupies space. It is made up of atoms and molecules, and can exist in various states such as solid, liquid, or gas. Matter interacts through forces like gravity and electromagnetism.
