Identify the correct statement about work energy theorem This question has multiple correct options
- A. work done by all the conservative forces is equal to the decrease in potential energy.
- B. work done by all the forces except the conservative forces is equal to the change in mechanical energy.
- C. work done by all the forces is equal to the change in kinetic energy.
- D. work done by all the forces is equal to the change in potential energy.
Step-by-step solution
The work-energy theorem states that the net work done by all forces acting on an object equals the change in its kinetic energy. Options A and B are also true statements but are corollaries of the theorem, not the theorem itself.
