Class 8 Science — Chapter 8: Force and Pressure
72 practice questions · 24 Easy · 24 Medium · 24 Hard
Practise Class 8 Science Chapter 8, "Force and Pressure", with 72 NCERT-aligned multiple-choice questions. The set is split into 24 Easy, 24 Medium and 24 Hard questions, so you can warm up on the fundamentals and then push into the exam-level problems that separate top scorers in CBSE Board exams.
"Force and Pressure" is one of the chapters where concept clarity across physics, chemistry and biology basics really pays off. Each MCQ on this chapter is timed and uses exam-grade marking (+2 correct, −1 wrong, 0 skipped), training the same accuracy-under-pressure that real papers demand. Every question carries a short explanation, so a wrong answer becomes a quick lesson rather than a dead end — the fastest way to close gaps before a test.
Use this chapter as targeted revision: attempt the Easy set first to confirm your basics on Force and Pressure, then move to Medium and Hard to test application and problem-solving. Your accuracy, streaks and XP save automatically, and the chapter feeds into your overall Class 8 Science mastery score. A few sample questions are shown below; sign in free to practise all 72.
Key concepts: Force and Pressure (Class 8 Science)
This chapter covers force and its effects, types of forces, pressure exerted by solids, liquids and gases, and atmospheric pressure.
- Force
- A push or pull that can change the speed, direction or shape of an object; a net force is needed to cause change.
- Types of force
- Contact forces (muscular, friction) and non-contact forces (gravitational, magnetic, electrostatic).
- Pressure
- Force acting per unit area; a smaller area gives greater pressure for the same force.
- Pressure in fluids
- Liquids and gases exert pressure on the walls and base of their container, increasing with depth.
- Atmospheric pressure
- The pressure exerted by the air around us; large but balanced by pressure inside our bodies.
Key formulas — Force and Pressure
💡 Exam tips for Force and Pressure
- Same force on a smaller area gives more pressure — that's why a sharp knife cuts better.
- Liquid pressure increases with depth and acts equally in all directions at a point.
Sample questions
Force acting per unit area is called:
Pressure = force ÷ area; it is the force acting on a unit area.
Two people push a box from opposite sides with 30 N and 20 N. The box moves in the direction of the:
Opposite forces subtract: 30 − 20 = 10 N net, in the direction of the larger (30 N) force.
A box weighing 200 N stands on the ground. Its base is 2 m². The pressure on the ground is:
Pressure = force ÷ area = 200 ÷ 2 = 100 N/m².
