Does it take more energy to walk down a flight of stairs or up?

up. but you use more muscles going down

You will of course have more Potential Energy at the top of the stairs. PE(grav) = H x M x g, where H is your height relative to the ground, M is your mass, and g is the acceleration of gravity (approximately 10 meters persec persec on Earth). Thus the higher you are, the greater the gravitational potential energy. So as you walk down the stairs, you decreasing your height relative to the ground, and thus lowering your PE. So what happened to the potential energy? Did it just disappear? No, the potential energy got converted into kinetic energy (you walking down the stairs) and also heat.\n\nJust as an additional note: the reason you have gravitional Potential Energy at the top of the stairs is because there is a gravitional force acting on you by the Earth. Of course when you are on the ground, there is still gravitional force acting on you. So when we talk about potential energy, we are talking about the potential energy difference between the top of the stairs and the ground, not some absolute number.

Stair climbing will work in two ways.\n\nFirst, you burn calories, which obviously helps.\n\nSecond, you build muscle tissue in your lower body.  Since the muscle groups in your lower body are the largest, they build up faster.  This is beneficial because for every extra pound of muscle that you add, you will burn about fifty calories per day, even if you don't do squat.\n\nA pound of fat contains about 2000 calories, so if you were to add 5 pounds of muscle, you would burn about one extra pound of fat about every eight days, not considering what you burn from the exercise.\n\nA lot of women are turned off by this idea, thinking that the extra muscle will be too obvious, but since you are working your lower body, it won't be.  Also, keep in mind that muscle is more dense than fat, so even if your weight doesn't change, you will look slimmer by toning up a bit.

Well, I read about a study that said that it doesn't matter what time you exercise but I do believe it is a lot better to do it in the morning.\n1-It'll be the first thing you do in the day, You will have more energy.\n2-It'll help you feel better through out the day\n3-If you exercises in the evening, you'll come home from work tired and you'll have this as a excuse for not doing any exercises.

The staircase effect refers to the positive or negative increase of muscle force during constant stimulation.

i'm taking a step aerobics class every monday and wednesday for an hour and i LOVE it! i've already lost a lot of weight and i can see how much more tone my body is.  the only negative is that when i used the taller step my knees started bothering me, but when i went back down a size it quit hurting. i highly recommend taking step because it's really made a difference in my body

Try using the stairs and the bicycle instead of the elevator or escalator and  the car.\nEat more proteins and complex carbohydrates.\nDrink juice or water instead of soda.\nYou could exercise also.\nI like to exercise at a gym because the other people there inspire me.

u fall down the stairs but if u fell up you'd go up the stairs faster

Does pressing the elevator button over and over make it come to that floor faster???    NO!

What works for me is exercise everyday ... a long walk does wonders.  I don't mean intense exercise, just something that gets you up and moving for an hour or so at a time.

stairs.  up & down...that will do it. \n\ngood luck

kinetic energy is related to her actual velocity, this stays the same according to the problem. \n\nGravitational potential energy increases the farther you get away from the earth. This is going up as the elevator rises.\n\nSo, 4 is correct.

Walking is a better fat burner.  It attacks the fat rather than the sugar.  Be sure to do about 45 minutes of it each time.

Yes, even though you're not running as much this should keep you or put you back in the shape that you want. Also you could walk a little more. buy those step counters and try to walk a specifc amount of steps. Have fun.

Well it depends on a number of factors, but I will try and make some educated assumptions.\n\nAssumptions:\n1) each story is 3 meters\n2) the rise of each step is the same as the depth\n3) The width of each stair area is 1 meter\n4) There is a 2x1 meter platform for changing directions at the top of each stair section.\n5) you move in the middle of the stair.\n\nUsing these assumptions, for each stair case you move horizontally 1/2+1/2=1 meter on the platforms and 3 meters on the stairs.  You also move 3 meters on the stairs.  Therefore you move 3√2 meters on the stairs and 1 meter on the platform.  Once you get to the next platform you will move one meter over (to be aligned in the middle of the next staircase).  Therefore you move 1+3√2+1=2+3√2 meters for each staircase.  There are two staircases per floor so you move 4+6√2 meters per floor.\n\nIf you start on floor 1 and go to floor 26 you have gone up 25 floors, and therefore you have moved 25(4+6√2)=100+150√2≈312 meters.\n\nIf you start on a base floor (that isn't 1) and go to floor 26, you have gone up 26 floors and have moved 104+156√2≈324 meters.\n\nThis of course feels like more work than walking 324 meters because you are going up.  It's much harder to work against gravity.\n\nWhatever it is, it sounds like a good workout, especially if you do it everyday.
