NCERT Class 11 Physics Chapter 5 Work, Energy and Power Test Mock Test
This free online test covers Chapter 5, Work, Energy and Power, from the NCERT Class 11 Physics Part I textbook. The 28 questions are written directly from the chapter — definitions, processes, worked examples and the points the book italicises — so a score here tells you how much of the chapter actually stuck, not how well you guess. Each answer carries an explanation that says why the right option is right and why the other three fail, which is where most of the learning happens. Attempt it after your first read of the chapter, then again before the exam. There is no negative marking, and you can review the full solution the moment you submit.

Sample Questions
Q1.The scalar or dot product of two vectors A and B is defined as A.B = A B cos theta, where theta is the angle between them. Which statement about this product is correct?
- AIt is a scalar quantity with no direction, even though each of A and B has a direction, and it is zero when A and B are perpendicular
- BIt is a scalar quantity that can never be negative
- CIt is a scalar quantity that is zero only when one of the two vectors is itself zero
- DIt is a vector quantity whose direction is perpendicular to the plane containing the two vectors
Q2.The work-energy theorem, as stated in the chapter, says that:
- AThe change in potential energy of a particle is equal to the work done on it by the net force
- BThe change in kinetic energy of a particle is equal to the work done on it by the net force
- CThe kinetic energy of a particle is always equal to the work done by the applied force alone
- DThe work done by the net force on a particle is always zero
Q3.A drop of mass 1.00 g falls from a height of 1.00 km and hits the ground with a speed of 50.0 m s-1. Taking g as 10 m/s^2, the work done by the gravitational force and by the unknown resistive force are respectively:
- A1.25 J and -10.0 J
- B-10.0 J and 8.75 J
- C10.0 J and -8.75 J
- D10.0 J and -1.25 J
