Does Walking Transfer Energy to the Ground?

AI Thread Summary
Walking does transfer a small amount of energy to the ground through footfall, but it does not result in a gain of mass for the Earth. Instead, the ground may experience a slight change in rotational energy based on the direction of movement. The momentum transferred to the ground is equal to the momentum gained by the walker, but the energy received by the ground is minimal. Most of the energy from walking is absorbed by the individual. Overall, while energy transfer occurs, its impact on the Earth is negligible.

When I walk do I transfer energy to the ground via my foot, if so would the ground/earth than gain an extremely small amount of mass because e=mc2

It won't gain mass, but will either gain or lose a tiny bit of rotation (dependent upon the direction in which you're walking). It's more the "equal and opposite reaction" concept than the "e=mc2" one.
 
Thanks but do I still transfer a bit of energy to the ground.
 
Yes, the same amount that it transmits to you. When I wrote "rotation", I was implying "rotational energy". I should have been clearer.
 
Thank you very much.
 
The momentum you transfer to the ground is the same as the momentum that you gain. The energy is different though. The ground only receives a very tiny fraction of the energy. Nearly all of it goes into you.
 
Thread 'Is there a white hole inside every black hole?'

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Is Gravity an entropic property like Surface Tension'

Why do two separately floating objects in a liquid "attract" each other ?? What if gravity is an emergent property like surface tension ? What if they both are essentially trying to *minimize disorder at the interfaces — where non-aligned polarized particles are forced to mix with each other* What if gravity is an emergent property that is trying to optimize the entropy emerging out of spin aligned quantum bits
