Matter is the stuff of the universe, and is everything that we can (and can't) see. Mass is the amount of matter in an object (a relation to matter). Volume is how much space the matter takes up (also relating to matter).

Matter is anything that has mass and occupies space. What is mass? Anything that opposes a change in motion. examples of matter: atoms, molecules, electrons, protons, neutrons, positrions (actually this is called anti-matter, a form of matter).

Matter is anything with mass (inertia). We are still learning about new kinds of matter (dark matter) and the role of Higgs bosons in creating the inertia. Your question is a good one. The more physics I learn, the less I understand.

Matter and energy are related to each other at the atomic level. Energy and matter are also associated to each other at much larger scales of nature. The laws of thermodynamics describe some of the associations between energy and matter as they relate to the Universe.

Since all matter is made up of atoms that have positive and negative charges, how can an object be neutral? Explain. thanks Well, if the number of postive equals the number of negative, we define that as neutral. They spread evenly in matter, so no net charge can be found.
