About This Topic

Students will define pressure as force per unit area and apply this concept to understand how pressure is exerted by solids.

Key Questions

1. Explain how the same force can produce different pressures depending on the contact area.
2. Analyze why sharp objects exert more pressure than blunt ones.
3. Predict the pressure exerted by an object given its weight and contact area.
