Does Walking Transfer Energy to the Ground?

[Berney123]

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.

 

[Danger]

Yes, the same amount that it transmits to you. When I wrote "rotation", I was implying "rotational energy". I should have been clearer.

 

[Berney123]

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.
