## Main Question or Discussion Point

Two wrestlers are pushing each other. Initially the wrestlers are at rest, however the small wrestler starts to move. Now in either cases, which wrestler exerts more force? My professor said that both exert the same amount of force on each other. This is really confusing as if they are applying equal forces on each other, how are they moving. Also say if the larger wrestler exerts 200 N and the smaller exerts 100 N, wouldnt the forces cancel out? If the larger one exerts 200 N, the smaller one then exerts the same force back right (the reaction force). The smaller wrestler exerts 100 N, then the larger would exert back the 100 N ( again Newton's Third Law). Doesnt this cancel out all forces, then how is there motion?
