Pressure Calculations

What is the equation used to calculate pressure?

• pressure= force/mass
• pressure =mass/volume
• pressure=area/force
• pressure=force/area

What decreases as you go up in the atmosphere?

• Altitude
• Atmosphere
• Meteors
• Air Pressure

What pressure will a force of 4000N exert on an area of the ground if each foot is 40cm²?

• 40 N/cm²
