- Pressure is foce in a specific area
- Pressure in a liquid
- force applied on an object by liquid
- Depends on depth
- salt water has less pressure
- $$Liquid pressure = density * grav accel * depth$$
- Buoyancy
- Loss of weight when in liquid
- Support force by water
- [[Atomic Nature of Matter]] shows it pushes against solid pushing it up
- force vectors at side cancel out, vs gravity
- Depends on density
- Equal to the weight of water it displaces
- Liquids have different densities
- Pressure is consistent in all fluids (liquid + gas)
