| Buoyant Force | when a fluid exerts an upward force on an object immersed in it |
| Archimedes' Principle | The buoyant force on an object in a fluid is equal to the weight of the fluid displaced by the object |
| Pascal's Principle | The pressure applied to a fluid is transmitted unchanged throughout the fluid |
| Hydraulic lifts | The pressure exerted on a smaller cylinder gets transferred to a larger cylinder |
| Bernoulli's Principle | As the velocity of a fluid increases, the pressure exerted by the fluid decreases |
| Venturi effect | Fluids flow faster in narrower spaces; a reduction in pressure |
| Fluid | A substance that can easily flow (liquid, gas) |
| Density | mass per unit volume |
