Pressure
Physics: Edexcel IGCSE, topic 5.1.5
Pressure
Pressure is the force per unit of 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).
Test yourself on Pressure
If a force of 10N is exerted on an area of 3m2, what is the pressure exerted?
