What do we need to measure to calculate the pressure acting on a surface?
The size of the force and the area it acts upon
The size of the mass and the volume it occupies
The size of the weight and the height it falls from
The size of the speed and the distance it travels
What is the formula for calculating pressure?
Pressure = Force/Volume
Pressure = Force/Area
Pressure = Mass/Area
Pressure = Mass/Volume
What are the units of pressure?
N/m
