Since the change in kinetic energy is zero, it means that positive changes in the gravitational potential force is similar to the negative change of change in internal energy. Let’s say you have a mass of 75 kilograms (165 pounds). That means that the action of 1 meters will reduce your internal energy in 735 joules. Which is called employed.
Climbing stairs vs a staircase
Now let’s get back to the original question: What does the work-energy principle say about the stairs against a stairs climbing machine? Well, we’ve already made the physics to climb the stairs. This is the same calculation when you get a long 1 meters table or climb 100 stories – this amount is only different for height. But think you’ll stay in the same place as the stairs move under you. If someone measures your forward motion, they say your velocity is zero. Your height also does not change, so now the energy consolidation is like this:
It says that changing internal energy is also zero, which means you will not burn any calories. I mean, that’s not right … right? Then how do we carefully? I will use a good example based on This video is from Steve Hold. It keeps like this: think that you are climbing a loud escalator. Again, an observer on the ground see you holding back. However, we can also measure your speed from the reference frame of the escalator, and you will progress.
In fact, if the escalator has walls and ceilings, you can’t say you stay in place. You don’t know the stairs moving. Since stairs move on a constant speed (zero acceleration), it is an Infertial reference frame. In physics, any inertial reference frame as valid as any other reference frame – the basic laws of physics remain the same. So, from the sight of the escalator frame you THE Move and do work. It’s the same as if you walked a quitting frame.
But really, the stair climber is harder
I say the stairs up and down the stairs are the same – but they don’t. In fact, climbing 100 stories is easier than the equivalent distance of a staircase staircase. Does that seem crazy? It’s a little crazy. The reason they are different because the gravitational field (G) never always.
Remember, we define gravitational potential energy as U = mxgxy? That’s not wrong, but it’s a little misleading. In fact, the potential potential energy for the world-person system is defined as the following:
