Is Using a Stair Machine the Same as Climbing Stairs?

The change in kinetic energy is still zero, which means that the positive change in potential energy is the negative of the internal energy change in the potential energy. Let’s say that 75 kilograms (165 pounds) are mass. This means the change of 1 meter will reduce your internal energy up to 735 Joules. It was not a job.

Stairs vs. a staircase climber

Now we can return to the original question: What does the principle of work-energy say about stairs against the stairs? Well, we have already made a stair climb physique. If you fall on the 1-meter table or get 100 stories, if it’s just a different value for height, the same calculation. But think about where you stay in the same place when the stairs pass under you. If someone measures your move forward, they would say that your speed is zero. Your height doesn’t change, so the work-energy equation is now like this:

This says the internal energy change is zero, ie it means not to burn any calorie. I want to say that it can’t be right … right? How will we make it? I will use a nice example according to the Steve Kolden This video. It goes so: Imagine that you climb the escalator that moves downward. Again, an observer on the ground would see you in a stationary. However, we could measure your speed from the reference frame of the escalator and you will advance.

In fact, if the escalator was walls and a ceiling, you can’t say you stay in place. You didn’t know that the stairs were moving. This would be an inertial reference framework for stairs to move on a permanent speed (zero acceleration). In physics, any inertial reference frame is valid as any other frame – the main laws of physics remain the same. Thus, from the perspective of the escalator frame have moves and works. The same frame is the same as when walking.

But in fact, the stair mountaineist is even harder

I said the stair climber and climbing stairs were the same, but not. In fact, it is easier than the equivalent distance of the stairs climber to climb to 100 stories. Looks crazy? A little crazy. The reason they are different, according to the field of gravity (g) Never permanent.

Remember, gravity has set potential energy U = MXGXY? It’s not really wrong, but it’s a little wrong. In fact, an attractive potential energy for the location system will be determined as follows:
