1. The problem statement, all variables and given/known data When I drag my feet on the ground (on a frictionless surface), there will be an equal but opposite force acting on another body. What is that body exactly? 2. Relevant equations none 3. The attempt at a solution Will it be transferred to some other parts to my body? So in space if i apply i push force the force will be transferred to some other part causing it to rotate? So it means that i might have translational equlibrium but i have a net moment so i can still rotate? thanks!
