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.

- Q1Easy
A push or a pull on an object is called a:
A.MassB.Force✓ CorrectC.SpeedD.VolumeAnswer: B. Force
Explanation: A force is a push or a pull acting on an object.
- Q2Easy
Force acting per unit area is called:
A.WeightB.EnergyC.Pressure✓ CorrectD.MassAnswer: C. Pressure
Explanation: Pressure = force ÷ area; it is the force acting on a unit area.
- Q3Easy
The force that pulls all objects towards the Earth is:
A.Muscular forceB.FrictionC.Magnetic forceD.Gravity✓ CorrectAnswer: D. Gravity
Explanation: Gravity (gravitational force) pulls objects towards the centre of the Earth.
- Q4Easy
The pressure exerted by the air around us is called:
A.Muscular pressureB.Liquid pressureC.Atmospheric pressure✓ CorrectD.Magnetic pressureAnswer: C. Atmospheric pressure
Explanation: The air (atmosphere) presses on everything; this is atmospheric pressure.
- Q5Easy
Liquids exert pressure on:
A.The bottom onlyB.The bottom and walls of their container✓ CorrectC.The walls onlyD.NothingAnswer: B. The bottom and walls of their container
Explanation: A liquid exerts pressure on the base and the walls of its container.
- Q6Easy
The SI unit of force is the:
A.Newton✓ CorrectB.PascalC.JouleD.WattAnswer: A. Newton
Explanation: Force is measured in newtons (N) in SI units.
- Q7Medium
Two people push a box from opposite sides with 30 N and 20 N. The box moves in the direction of the:
A.30 N force, with net 50 NB.30 N force, with net 10 N✓ CorrectC.20 N force, with net 10 ND.It does not moveAnswer: B. 30 N force, with net 10 N
Explanation: Opposite forces subtract: 30 − 20 = 10 N net, in the direction of the larger (30 N) force.
- Q8Medium
Why do camels and some heavy animals have broad, flat feet?
A.To increase the area of contact, lowering the pressure on sand so they don't sink✓ CorrectB.To increase pressureC.To look bigD.To run faster onlyAnswer: A. To increase the area of contact, lowering the pressure on sand so they don't sink
Explanation: Broad feet spread the body weight over a larger area, reducing pressure so the animal does not sink in sand.
- Q9Medium
Which statement about gravitational force is correct?
A.It pushes objects away from EarthB.It acts only on contactC.It acts on all objects, pulling them towards the Earth, without contact✓ CorrectD.It needs a magnetAnswer: C. It acts on all objects, pulling them towards the Earth, without contact
Explanation: Gravity is a non-contact force that pulls every object towards the Earth.
- Q10Medium
It is hard to separate two stuck suction cups because:
A.They are gluedB.They are heavyC.They are magneticD.Atmospheric pressure outside pushes them together once the air between is removed✓ CorrectAnswer: D. Atmospheric pressure outside pushes them together once the air between is removed
Explanation: With air removed between them, the outside atmospheric pressure presses them firmly together.
- Q11Medium
A dam is built much thicker at its base than at the top because:
A.It looks betterB.To save materialC.Water pressure increases with depth, so the base must withstand greater pressure✓ CorrectD.Water is lighter at the bottomAnswer: C. Water pressure increases with depth, so the base must withstand greater pressure
Explanation: Since liquid pressure rises with depth, the base experiences the most pressure and must be strongest.
- Q12Hard
Forces of 12 N (right) and 7 N (left) act on a block, plus 5 N (left). The net force is:
A.24 N to the rightB.0 N, the block stays at restC.10 N to the leftD.0 N✓ CorrectAnswer: D. 0 N
Explanation: Right = 12 N; left = 7 + 5 = 12 N. They are equal and opposite, so the net force is 0 N.
- Q13Hard
A box weighing 200 N stands on the ground. Its base is 2 m². The pressure on the ground is:
A.400 N/m²B.100 N/m²✓ CorrectC.202 N/m²D.198 N/m²Answer: B. 100 N/m²
Explanation: Pressure = force ÷ area = 200 ÷ 2 = 100 N/m².
- Q14Hard
Two magnets are brought near each other and repel without touching. This demonstrates that:
A.A non-contact force (magnetic) can act across a gap✓ CorrectB.It is a muscular forceC.Forces always need contactD.It is gravityAnswer: A. A non-contact force (magnetic) can act across a gap
Explanation: Magnets exert force across a gap, proving magnetic force is a non-contact force.
