CAIE IGCSE Physics 1.8.1 Pressure As Force Per Unit Area Questions

Practise calculating pressure using p = F/A and analysing how force and contact area affect pressure with CAIE IGCSE Physics questions and mark schemes.

Exam points

Calculate pressure using p = F/A and analyse how force and contact area affect pressure.

[Maximum number: 2]

A car has a weight of 13000 N . The car is supported by 4 tyres. The area of each tyre in contact with the road is $0.016 \mathrm{~m}^{2}$ .

Calculate the pressure on the road due to the weight of the car.

pressure =

$2.0 \times 10^{5} \mathrm{~Pa}$ OR 200000 Pa OR 200 kPa
( P= ) F / A OR $13000 /(0.016 \times 4)$
