What to expect: This mock test covers key concepts from the Force, Turning Effects of Force, and Uniform Circular Motion chapter — including application-based and competency-focused questions aligned with how ICSE actually sets the paper.
Tip: Attempt without notes first to identify gaps, then review explanations for any wrong answers. Retake after a few days for best retention.
Sample questions
-
1.Define the centre of gravity (C.G.) of a body. Which of the following statements correctly describes it?
- A.The point where the body balances perfectly, regardless of its orientation.
- B.The geometric center of the body, calculated as the average of all particle positions.
- C.The point where the body's mass is concentrated, but only in a uniform gravitational field.
- D.The point where the sum of all forces acting on the body equals zero.
-
2.How can the principle of moments be verified using a metre rule, a fulcrum, and a weight box? The principle states that for equilibrium, the sum of anticlockwise moments equals the sum of clockwise moments.
- A.Balance the rule on the fulcrum, hang weights on both sides, and adjust distances until moments balance.
- B.Place all weights on one side and measure the rule's tilt angle.
- C.Suspend the rule from one end and add weights until it becomes horizontal.
- D.Rotate the rule around the fulcrum and record the time for one full swing.
-
3.While a force changes the linear motion of a body, what effect does the moment of a force produce?
- A.It changes the mass of the body.
- B.It produces a change in the rotational motion of the body.
- C.It increases the speed of the body in a straight line.
- D.It reduces the friction acting on the body.
-
4.A force of 2.5 N with its arm 0.5 m long rotates a spanner in a clockwise direction. What is the torque?
- A.1.25 N m (clockwise)
- B.1.0 N m (clockwise)
- C.1.5 N m (clockwise)
- D.2.0 N m (clockwise)
-
5.Why are racing cars designed to be very broad and very low in height?
- A.To increase the centre of gravity for better aerodynamics
- B.To keep the centre of gravity very low, ensuring stability during sharp turns at high speeds
- C.To reduce the weight of the car for higher speeds
- D.To allow for larger fuel tanks and more power
