when you walk the reaction of your thrust is the Earth going very slightly in the other sense
but how can an ice skater that having the skates perfectly parallel while thrusting pushes sidewards and advances forward besides taking into account that being the skates parallel the longitudinal force tends to 0
so is the ice skating keeping the skates parallel to thrust a case where the reaction is sidewards instead of backwards or what?
how is the Earth pushed backwards by the ice skater while keeping the skates parallel and thrusting sidewards to go forward?
