Pressure & Force on Container
Physics: AQA GCSE Higher, topic 5.4.1
Pressure
Pressure is the force per unit of area. This relationship can be rearranged to calculate force by multiplying the pressure by the area.
Force on container
- In fluids (liquids or gases), the particles collide with the walls of their container.
- The particle exerts a force on the container and the container exerts a force on the particle.
Force at right angles
- The force exerted on the surface in contact with the fluid particle will be at the normal to the surface (at right angles).
