| momentum | The product of an object's mass and velocity. |
| law of conservation of momentum | The rule that the total momentum of objects in an interaction does not change. |
| pressure | The force exerted on a surface divided by the total area over which the force is exerted. |
| pressure | The force of a gas's outward push divided by the area of the walls of the container. |
| pascal | A unit of pressure equal to one newton per square meter. |
| fluid | Any substance that can flow and easily change shape. |
| Pascal's Principle | The rule that when force is applied to a confined fluid, the increase in pressure is transmitted equally to all parts of the fluid. |
| hydraulic system | A system that multiplies force by tansmitting pressure from a small surface area through a confined fluid to a larger surface area. |
| Bernoulli's principle | The rule that a stream of fast-moving fluid exerts less pressure than the surrounding fluid. |
| equilibrium | A state in which opposing forces in a system are equally balanced or stable. |
| calculating pressure | force/area |
