Force per unit area 1 of 11 The bigger the area, the _______ the pressure lower 2 of 11 The bigger the force, the _______ the pressure higher 3 of 11 What is the formula for pressure? Pressure (Pa) = Force (N) / Area (m^2) 4 of 11 What is density? Mass per unit volume 5 of 11 What is the formula for density? Density (kg/m^3) = Mass (kg) / Volume (m^3 6 of 11 If something's density > 1, does it float or sink in water? Sink 7 of 11 If something's density < 1, does it float or sink in water?
