Plain-English Meaning
Pressure is the perpendicular force exerted per unit area.
Mechanics questions usually become easier once you identify whether the problem is about force balance, kinematics, energy, or conservation.
Deeper Explanation
Pressure is the perpendicular force exerted per unit area.
Worked Example
Problem: A 600 N person stands on one heel of area 1.5 cm². Find the pressure.
- A = 1.5 × 10⁻⁴ m²
- P = F/A = 600 / 1.5×10⁻⁴
- P = 4 × 10⁶ Pa = 4 MPa
Result: 4 MPa
