Is there work done whenwhen sleeping and walking?

Question

Please help me and give me the reasons pls...

BTW, work done is a force is equal to the force multiplied by the distance moved in the direction of the force.

Answer 1

For sleep, I'm not sure, but for walking there definitely is work being done. When we walk, friction keeps us from slipping. Walking at a constant pace implies use of a constant force to keep friction from slowing us down or even keeping us from moving. The constant force is used over a distance, which is why we are doing work.
