Free online mock test for Work, Energy and Power (ICSE Class 10 Physics) — 20 competency-based questions based on the latest CISCE 2027 syllabus, with instant marking. Try the samples below, then take the full test free.
What to expect: This mock test covers key concepts from the Work, Energy and Power 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.Kilowatt hour is the commercial unit of :
- A.electric force
- B.electric power
- C.electric energy
- D.none of these
-
2.A hydroelectric power station takes its water from a lake whose water level is at a height of 50 m above the turbine. Assuming an overall efficiency of 40%, calculate the mass of water which must flow through the turbine each second to produce power output of 1 MW. (g = 10 m s⁻²).
-
3.When a body moves in a circular path, how much work is done by the body?
- A.Zero, because the centripetal force is perpendicular to the displacement at every point.
- B.Maximum, since the body is continuously moving and force is applied.
- C.Equal to the product of centripetal force and the radius of the path.
- D.Half the kinetic energy of the body, as work depends on velocity.
-
4.A force acts on a body and displaces it by a distance of 10 m in the direction of the force. If the work done by the force is 9000 J, calculate the force applied.
-
5.An electrical heater is rated 4 KW, 220 V. Find the cost of using this heater for 12 hours if one kWh of electrical energy costs ₹ 3.25.
