Answer:
Answer: [tex]\green…
Explanation:
Answer:
If you go up and down an incline with a a constant speed, you are doing same amount of work, while going up to go up against gravity and while coming down to keep your speed from increasing.
Now coming to steps, while going up, we need to push ourselves to go up, while coming down we can afford to fall down onto each step, and the step absorbs a part of our energy. So although we might find it easier, we are really impacting our bones and the steps and make them continuously collide.
Imagine a ball, a small push from top and it rolls down the steps. Now imagine the steps are covered with rough carpet. The ball does not really accelerate a lot while coming down. Now if we had to send the ball up, we need quite a bit of initial push.
Explanation:
That is because whenever you are climbing up the stairs you are doing work against the gravity but when you climb down you do work with the gravity.
And doing work against gravity consumes more energy than doing work with the gravity.;>
