What unit is pressure measured in?
It's named after a famous scientist.
What is the unit of pressure?
Remember the name associated with pressure measurement.
Increasing the area over which a force is applied will lead to increased pressure.
Think of the relationship between force, area, and pressure.
A box with dimensions 2m x 1m x 1m is resting on a surface. If it weighs 2000 N, calculate the pressure exerted by the box on the surface.
Compute the area and then apply the pressure formula.
You have two surfaces: one is smooth and the other is rough. If the same force is applied to both, which surface will experience a higher pressure and why?
Consider how surface characteristics affect area and the application of force.
