We could use (force x distance) to calculate the work, or (mass x gravity x height). Let's avoid using the force (weight) since it involves looking up another unit and carrying out another step in the arithmetic. Note: We have to assume that the given 440 m is the net vertical rise of the stairs, since the question tells us nothing about their slope or pitch. On that basis, we also note that this is one heckuva climb, being within 10 ft of the officially listed height-above-street for the Willis (Sears) tower in Chicago, and not made any easier by the fact that our climber is no lightweight. (110 kg weighs about 243 lbs.) But we're not going to worry about any of that; we'll just crunch the numbers given. Work = change in potential energy = M x G x H M = 110 kg G = 9.78 m/s2 H = 440 m M x G x H = (110 kg x 9.78 m/s2 x 440 m) = (110 x 9.78 x 440) (kg - m2 / s2) = 473,352 Newton-meter = 473,352 Joules If our hero can lift his weight at the rate of one horsepower, this quantity of work will take almost 11 minutes. Another Note: This is the net increase in gravitational potential energy due to having changed the elevation of his 110 kg of mass. But the man is certain to have expended a whole lot more energy than this in the effort, and we have no way of knowing exactly how much. It all depends on the style, form, and efficiency of his stair climbing technique. No two people are the same, which is why some can run a marathon without breaking a sweat, while I have to slow down and take deep breaths after typing a long Wiki.Answer like this one on the keyboard.

What type of workout equipment can be found in a gym that simulates climbing stairs?
A stair climber or a step machine is the workout equipment found in a gym that simulates climbing stairs.
Is work done on climbing stairs?
Yes, work is done when climbing stairs. Work is defined as force applied over a distance, so when you lift your body against gravity while climbing stairs, you are exerting force over a distance. The energy expended to lift your body is considered work.
What are the differences between using a StairMaster and climbing regular stairs for cardiovascular exercise?
Using a StairMaster provides a consistent and controlled workout, while climbing regular stairs offers a more varied and natural movement. The StairMaster may be easier on the joints, but climbing stairs engages more muscles and can provide a higher intensity workout.
Is climbing stairs an example of work?
Yes, climbing stairs is considered an example of work in a physics context. Work is done when a force is applied to move an object over a distance in the direction of the force. In this case, you are exerting a force to move your body against the force of gravity while climbing stairs.
Is there some limit to the height of the flight of stairs used and the horsepower developed?
There's no limit to the height of the stairs, but because power is the rate of doing work, different people would run up several flights of stairs at different rates, since each person has a "limit" on the amount of power she/she can produce.
Would a person with emphysema have trouble climbing stairs?
Yes
When was Climbing the Stairs created?
Climbing the Stairs was created in 2008.
What is better for burning belly fat... jogging or climbing stairs?
Climbing stairs
How long would a 60 watt light bulb have to burn to produce the energy you used climbing the stairs?
If you weigh 70 kg and the stairs are 3 metres high, the energy needed is 70 x 9.8 x 3 Joules or 2058 joules. That would keep a 60 w bulb going for 2058/60 seconds, or 34.3 seconds. But to produce that same energy in a generating plant, the fuel energy wasted in the process would be between 2000 joules for a gas plant of 50% efficiency, and 6000 joules for a coal plant of 25% efficiency.
