Why is going up a flight of stairs more tiring than going down?

Answer 1

going up a flight of stairs, u have to use enough energy to equal gravity and your weigh. while going down a flight of stairs u just use enough energy to lift your leg up and you let gravity do the rest

Answer 2

Going up a flight of stairs: against the gravity. Going down: with the gravity. Thus the gravitational force tires us more while going up. Ask Mr. Isaac Newton and his apple for more... ;)

Answer 3

on no account had the prefer to push somebody down the stairs, yet each so often hassle approximately loosing my footing as I definitely have only a splash a historic previous of going **** over tit with my ankles spontaneously twisting and spraining. i might say in case you have an urge to easily push any random individual down a flight or 2 of stairs which you're able to rather get some help.

Answer 4

this is because when we go up the stairs we go against the force of gravity
the gravity pulls us down as we go up

Answer 5

Because you're moving something against gravity and having to overcome it; when you're walking downstairs, you're simply having to control the "fall" of your body weight, rather than having to use enough energy to overcome the pull of gravity.

Answer 6

When we raise anything against the force of gravity, work is done, additional to that of movement alone, not so when descending stairs.

Answer 7

It takes more energy to move the body up an incline than down one.

Answer 8

Wow, see, this proves it, there are stupid questions.

And I also see 3 out of the first 5 replies have the word "you're" spelled "your". Time to figure that one out kids...

Answer 9

Your using your bodies' power to hike up those legs, going down requires no power, just stopping power!

Answer 10

because your using your muscles more as your carring your weight up
