Matter is a substance that has inertia and occupies physical space. According to modern physics, matter consists of various types of particles, each with mass and size. The most familiar examples of material particles are the electron, the proton and the neutron. Combinations of these particles form atom s.
Matter is anything that has mass and takes up space. It includes all the physical âstuffâ around usârocks, houses, water, air, people, ants, trees, etc. All matter can exist as a solid, a liquid, or a gas.Matter includes all the things we can weigh (to find the mass) and measure to find the volume (because they take up space). Different substancesâdifferent types of matterâhave different properties that can be used to distinguish them from each other.ll matter can exist as a solid, a liquid, or a gas.
