A series of free GCSE/IGCSE Physics Notes and Lessons.
The following diagram gives the formula for pressure: pressure = force ÷ area.
How to calculate the pressure of fluid acting at a surface?
Explain why atmospheric pressure decreases with an increase in height.
Example:
A gas inside a container applies a force of 400 000N. THe walls of the container have an area of 8 m2. Calculate the pressure of the gas.
