Question

If we are travelling uphill, why do we require large amount of force?​

Answer 1

Answer:

This is due to its force of gravity. When we get away from the earth's surface, we have to do more work to overcome the force of gravity. On the other hand when we come down from a height, the gravitational pull helps our movement. ... The steeper the climb, the more is the work to be done.
