A horse pulls upon a wagon, but according to Newton’s third law the wagon pulls back with an equal and opposite force upon the horse. How then can either the wagon or the horse move?
I'm supposed to draw a free body diagram but I'm not sure on the forces.?
<<<<< Force on the horse by the wagon
>>>>> Force on Hourse by road
>>>>> Force on wagon by horse
the body moves because the horse applies a force to it that is not balanced. The force the body exerts on the horse is not counted as a force on the body.
