Work, Energy and Power MCQ: Learn the most important multiple choice questions from the topic - Work, Energy and Power. These questions help in your NEET 2023 preparation.
Work, Energy and Power are fundamental concepts of Physics. Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time. This article discusses...
The kinetic energy gained by the ball is equal to the work done on it. Therefore, the ball gains 50J of kinetic energy. Since the question asks for the amount of kinetic energy gained from the player, the correct answer is 0.5J.
