Q3. Compare the two different scenarios of getting a heavy piece of furniture up five steps to the main entrance door of a house.
(a) Lifting the heavy piece of furniture and carrying it up the five steps.
(b) Using a long ramp to push the heavy piece of furniture up to the main entrance door of a house.
What is the work done by gravity in either scenario? What is your work done in either scenario? Is there any other work involved?
