Momentum Transfer: Does Light Mass Gain Momentum?

AI Thread Summary
The discussion centers on the concept of momentum transfer in a mechanical system involving two masses (M1 and M2) and a gear mechanism. When momentum is imparted to M2, it also affects M1, leading to a transfer of momentum to the entire system. If M1 collides with a heavier body that is not rigidly attached, the body will gain momentum due to the interaction. The participants agree that motion must be transferred as momentum has been imparted, confirming the dynamics of the system. The conversation emphasizes the importance of understanding momentum transfer in relation to mass and motion.

The blue ball is a gear actually, with 2 racks on both its side which are attached to 2 masses each (M1 = M2).

If momentum is made to gain in the arrangement from the side M2...it will also impart momentum to M1.

Suppose all this happens in a body to which the whole arrangement is attached.

And this motion is stopped by colliding M1 to this body itself.

Will this body gain momentum (if its light)?

Assume the body to be heavier than M1+M2
 
Is this forum active?
 
as long as the body is not rigidly attached to the system given in the picture, it will move.
 
Same opinion with me...actually that can't happen cause momentum has been imparted...M1 and M2 cannot be rigidly attached.

So motion has to be transferred.

Thanks for confirming.
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?

Thread 'Free fall of person in a sled to direct horizontal motion by atmospheric resistance'

Let there be a person in a not yet optimally designed sled at h meters in height. Let this sled free fall but user can steer by tilting their body weight in the sled or by optimal sled shape design point it in some horizontal direction where it is wanted to go - in any horizontal direction but once picked fixed. How to calculate horizontal distance d achievable as function of height h. Thus what is f(h) = d. Put another way, imagine a helicopter rises to a height h, but then shuts off all...
