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 'Why can't Solar panels be hemispherical, or a curved strip type?'

comparing a flat solar panel of area 2π r² and a hemisphere of the same area, the hemispherical solar panel would only occupy the area π r² of while the flat panel would occupy an entire 2π r² of land. wouldn't the hemispherical version have the same area of panel exposed to the sun, occupy less land space and can therefore increase the number of panels one land can have fitted? this would increase the power output proportionally as well. when I searched it up I wasn't satisfied with...
