Work and energy questions

All these questions are provided with correct answers. A man is carrying the heavy luggage from one platform to the other of a Railway station but still according to the logics of science his work done is said to be zero. Can you opt out the correct reason? Answer: b The force is acting perpendicular to the direction of displacement of luggage. When a body like earth is moving in a circular path the work done in that case is zero because:. A car is accelerated on a leveled road and attains a velocity 4 times of its initial velocity.

Which of the following statements are true about work? Include all that apply. TRUE - Work is a form of energy, and in fact it has units of energy. FALSE - Work is not dependent on how rapidly the force displaces an object; power is time-based and calculated by force multiplied by speed. FALSE - Since Superman does not cause a displacement, no work is done; he is merely holding the car to prevent its descent down the hill. TRUE - There is a component of force in the direction of displacement and so this is an example of work. TRUE - There is a force and a displacement; the force acts in the opposite direction as the displacement and so this force does negative work.
