Work,Power and Energy

These two tests are on Work, Power, and Energy is designed to help JEE aspirants master one of the most fundamental topics in physics. It includes 2 tests with 10 questions each having carefully selected multiple-choice questions that cover essential concepts such as work done by a force, kinetic and potential energy, power, energy conservation, and spring systems. Each question tests conceptual clarity, application skills, and numerical accuracy—key for success in competitive exams. Practicing this test will strengthen problem-solving speed and boost confidence. It serves as an excellent tool for revision, self-assessment, and identifying weak areas before the actual JEE examination.
