Force
A push or pull that causes changes in movement
Hydrodynamics
The movement of liquids around solid objects
Kinetic Molecular Theory
A theory that states:
- All matter is composed of molecules or other types of particles.
- Particles are in constant motion
- There are forces of attraction among particles
