Pressure
Definition: The force exerted on a surface divided by the total area over which the force is exerted.
Equation: Pressure = Force/Area
Pascal = 1N/m²
Math Solution: Who exerts more pressure on the ground, a 700N woman standing in high heels with a total area of .008 m², or the same woman standing in work boots with a total area of .06 m²? Calculate the pressure she exerts on the ground in both cases.
Answer: P = F/A, so High Heels - 700N/0.008m² = 87500N/m² = 87500-Pa, Work Boots - 700N/0.6m² = 11666.6N/m² = 11666.6-Pa, so the High Heels exert more pressure on the ground.
