               Vishal and Shivam were observing a building having two different staircase. One slanting and other vertically spiral. Vishal was of the opinion that a person using slanting staircase will be doing more work against gravity but Shivam thought otherwise. They started quarrelling. Their friend Aman explained and gave entirely different view and specified them. Read the given passage and answer the following questions (a)What according to you was the explanation given by Aman? (b) What appreciable values do you see in the Aman?          

Answer:

   (a) Aman explained that the energy required in both the cases is equal because whenever the work is done against gravity, the amount of work done is equal to the product of weight of the body and the vertical distance through which the body is lifted, not on the path followed (work done in lifting a body = weight of body x vertical height).                           (b) Aman has problem-solving and conceptual values.
