Forces, Fluids, Density

3. A state of matter with no definite shape or volume, expanding to fill its container.
4. Force: The upward force exerted by a fluid on an immersed object.
8. Pushes or pulls that can change the motion of an object.
10. A property of materials that do not change volume under pressure.
11. A measure of a fluid's resistance to flow; thicker fluids have higher viscosity.
12. The mass per unit volume of a substance.
13. The amount of matter in an object, not dependent on gravity.
15. The measure of the surface of a shape or object.
16. A state of matter with a definite volume but no definite shape, taking the shape of its container.

1. The act of pressing or squeezing a material to reduce its volume.
2. Substances that flow and take the shape of their container, including liquids and gases.
3. The force that attracts objects toward each other, especially toward the center of the Earth.
5. A state of matter with a definite shape and volume.
6. The amount of space an object or substance occupies.
7. The force exerted per unit area.
9. The force exerted by gravity on an object's mass.
14. Theory: The idea that all matter is made up of tiny particles that are in constant motion.
