What is Pressure?

Pressure is the perpendicular force exerted per unit area.

Formula: P = \frac{F}{A}

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
