Why can't we feel any force unless that force is opposed by other forces ??
E.g. we don't feel our weight unless we stand on rigid bodies or other supports . When we are in air or when we jump from a height we feel weightless because there is no force opposing our weight.
So my question is why and how do such crazy things happen ?
Observation : I have felt this effect even while I was on my bicycle. When I was accelerated by the paddling faster , I barely felt any restriction in paddling and the paddles were rotating smoothly i.e. I couldn't feel any opposition . But due to the existence of rolling friction the tires slow down and paddling becomes harder and I could feel that hardness while driving.
Does this mean that we need a force in opposite direction of an existing force to feel that existing force ??
Is it proper to correlate the example and the observation ?
