Is Using a Stair Machine the Same as Climbing Stairs?

Since the change in the speed of speed is still zero, the positive change of gravitational potential energy is equal to the negative of the change in internal energy. Let’s say you have a mass of 75 kg (165 pounds). This means that moving above 1 meter will reduce your internal energy by 735 jol. It’s called Working Out.

A staircase vs. a staircase

Now we can go back to the original question: What is the work-power policy on the ladder vs.-climing machine? Ok, we’ve already done the stairs to the physics of climbing. If you are at the top of a 1 meter table or get up in 100 stories this is the same count – it’s just a different value for height. But suppose you are in the same place when you are under the stairs to you under. If someone measures your forward speed, they will say that your speed is zero. If your height is also not changing, so now the work-power equation looks like it:

It says that the internal energy change is also zero, which means you will not burn Any Calorie. I mean, it can’t be right … isn’t it? So how do we fix it? I’m going to use a great example based on This video from Steve moldThe It is like this: Imagine you are climbing a low-moving escalator. Again, an observer on the ground will see you as steady. But we can also measure your speed from the reference frame of the escalator and you will rise above.

In fact, if there is a wall and a ceiling, you can’t say that you are in the place. You didn’t even know that the stairs were on. Since the stairs are moving at a constant velocity (zero acceleration), it will be an inanimate reference frame. In physics, any inanimate reference frame is as valid as any other reference frame – the primary laws of physics remain the same. Thus, from the perspective of the escalator frame Is Getting up and working. It’s the same as you walk in a steady frame.

However, the stairs are more tough to the mountains

I said that the stairs were the same as mountaineers and climbing stairs – but they weren’t. In fact, the stairs climbing in 100 stories are easier than the distance equivalent to mountaineering. Does it look crazy? It’s a little crazy They are different because of the gravitational field (G) Not actually constant.

Remember, we’ve defined as gravitational potential forces U = mxgxy? This is not really wrong, but it is somewhat confusing. Indeed, gravitational potential power for the earth-person system will be defined as following:
