density + pressure

• Pressure is force per unit area.
• The equation to calculate pressure from force, area, and depth is P = F/A or P = mgh / V
• Density is the mass per unit volume.
• The SI unit of pressure is the pascal (Pa).
• Density is mass divided by volume (ρ).
• The equation to calculate the density of an object is ρ = m / v.
• The formula for calculating density is D = M/V
• the units of density are

  g/cm3 or kg/m3
• mass is the amount of matter in an


  object
• volume is the physical space an object

  occupies
• if the density of gold is 19.4 what is the mass of the block. - volume is 240

  mass on the top density and volume on bottom
