Study Notes
Pressure
- Pressure is the force applied per unit area.
Factors Affecting Pressure
- The weight of an object affects the pressure it exerts on a surface, with heavier objects exerting more pressure.
- The surface area of an object in contact with a surface affects the pressure it exerts, with larger surface areas resulting in less pressure.
Effect of Surface Area on Pressure
- If the surface area of an object is reduced, the pressure it exerts on a surface will increase.
Examples of Force and Surface Area
- An example of force being applied over a small surface area is a stiletto heel, which exerts a large amount of pressure on a small area.
