ICSE Class 10 Work, Energy and Power — Mock Test (2027)
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.An Ox can apply a maximum force of $1000\,\mathrm{N}$. It is taking part in a cart race and is able to pull the cart at a constant speed of $30\,\mathrm{ms}^{-1}$ while making its best effort. Calculate the power developed by the Ox.
-
2.Why is the kinetic energy of a body always positive, regardless of the reference frame?
- A.Because velocity is always positive in any reference frame.
- B.Because mass is a vector quantity and velocity is squared.
- C.Because velocity appears squared in the expression and mass is a scalar.
- D.Because kinetic energy depends only on the mass of the body.
-
3.An Ox can apply a maximum force of 1000 N. It is taking part in a cart race and is able to pull the cart at a constant speed of 30 ms⁻¹ while making its best effort. Calculate the power developed by the Ox.
-
4.Assertion : When the force retards the motion of a body, the work done is negative. Reason : Work done depends on angle between force and displacement.
- A.Both assertion and reason are true and reason is the correct explanation of assertion.
- B.Both assertion and reason are true but reason is not the correct explanation of assertion.
- C.Assertion is true but reason is false.
- D.Assertion is false but reason is true.
-
5.State the principle of conservation of energy. Which example best illustrates this principle?
- A.A car engine converting all fuel energy into motion without any loss
- B.A simple pendulum swinging, where potential and kinetic energy interchange but total energy remains constant
- C.A battery losing all its charge without any energy transformation
- D.A ball rolling on a flat surface coming to rest due to energy creation
