The discussion centers on whether action and reaction forces, as described by Newton's third law, lie on the same line. Participants explore implications for angular momentum, particularly in the context of a cat's ability to rotate in mid-air before landing.
Participants express differing views on whether action and reaction forces must lie on the same line, and the implications of this for angular momentum. The discussion remains unresolved, with multiple competing perspectives presented.
Participants have not reached a consensus on the necessity of action and reaction forces lying on the same axis, nor have they fully resolved the implications for angular momentum in the context of a cat's rotation.
The short answer is the cat is not a rigid body. Newtons Laws are inviolate and there are no external torques on the cat but by clever counterotation the cat can get her feet downward without offending Sir isaac.fxdung said:Do action force and reaction force(Newton's third law) lie on same line?If not then the angular momentum will be violated.I don't know why a cat falling can rotate itself before contact land if the conservative law of angular momentum not be violated?
