What is the formula for pressure?
Remember the components: force and area.
What unit do we use to measure pressure?
Think about the relationship to newtons and area.
What is the primary formula to calculate pressure?
Think about how force relates to area.
True or False: Increasing the area while keeping force the same will increase pressure.
Consider how the formula adjusts with area.
A cylindrical piston has a radius of 0.1 m. If a force of 2000 N is applied, what is the pressure exerted by the piston on the surface below?
Remember to compute the area of a circle before calculating pressure.
Two blocks of identical mass, 1 kg each, rest on surfaces of different areas: one has an area of 0.4 m² and the other has 0.2 m². Which block exerts more pressure and why?
Consider how pressure varies with area and mass.
