What is the pressure formula?Show answer
Pressure is worked out with this formula:
What are pressure in solids?Show answer
For solids, the key idea is area. The same force on a smaller area gives a higher pressure.
What are pressure in liquids?Show answer
In a liquid, pressure pushes in all directions, not just down. The pressure in a liquid gets greater the deeper you go, because there is more liquid above pushing down.
What are pressure in gases?Show answer
Gases also push out in all directions and exert pressure. The fast-moving particles of a gas hit the walls of their container and push on them.
