Free online mock test for Work, Energy and Power (ICSE Class 10 Physics) — 81 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.For a collision in two dimensions, conservation of the z-component of momentum (z perpendicular to the plane of final velocities) implies:
- A.The collision must be elastic
- B.The entire collision takes place in the x-y plane
- C.Kinetic energy is always conserved
- D.The two bodies must have equal masses
-
2.The total mechanical energy of a system is conserved if the forces doing work on it are:
- A.Frictional
- B.Conservative
- C.External only
- D.Time-dependent
-
3."In an elastic collision of two bodies, the momentum and energy of each body is conserved." This statement is:
- A.True
- B.False, because it is the TOTAL momentum and TOTAL energy of the system that are conserved, not those of each body individually
- C.True, because each body retains its own momentum
- D.False, because momentum is never conserved in collisions
-
4.Kinetic energy is:
- A.A vector directed along velocity
- B.A scalar measuring the work an object can do by virtue of its motion
- C.A vector directed along the net force
- D.A quantity that can be negative
-
5.Two identical ball bearings in contact rest on a frictionless table and are hit head-on by another identical ball bearing moving with speed V. If the collision is elastic, then:
- A.All three balls move off together with speed V/3
- B.The two struck balls stay at rest and the incoming ball rebounds with speed V
- C.The incoming ball stops and the farthest ball moves off with speed V, the other two staying at rest
- D.The incoming ball stops and the two struck balls each move off with speed V/2
