What is matter?
anything that has mass and takes up space
anything that takes up space and has force
anything that has mass and uses energy
anything that has volume and uses intertia
What is Volume?
The amount of matter in a solid, liquid, or gas.
Everything around you.
The amount of space an object takes up.
What statement is true?
Mass never changes. Weight does.
Weight never changes. Mass does.
Both mass and weight change because they are affected by gravity.
Neither mass nor weight change. They are always the same.
