Summary:
- Matter is all the “stuff” that exists in the universe.
- Everything you can see and touch is made of matter, including you.
- In science, matter is defined as anything that has mass and volume.
- Mass is commonly confused with weight.
- The two are closely related, but they measure different things.
- Whereas mass measures the amount of matter in an object, weight measures the force of gravity acting on an object.
- If the strength of gravity is held constant, then an object mass is directly proportional to the objects weight.
