    Newton's Third Law and a rocket in space

    I just want to make sure I properly understand Newton's Third Law. Assume there's a horse with a mass 100kg and a cart with a mass 20kg. Assume the horse pushes off the ground with a force 1,000N, the ground,in turn, will push the horse forward with a force of 1,000N. If I look a the system...

    Newton's Third Law and a rocket in space

    Yes accelerating forward. Is the rocket experiencing a force in the opposite direction because the object is intact; thus, able to provide that opposite force? Otherwise, if the object collapsed, the rocket would proceed through the object, with no opposite force.

    Newton's Third Law and a rocket in space

    Yes, we've established the system is moving forward. Now, to my question, the rocket will experience a force in the opposite direction equal to the force it is applying to the object - this is the force pair that I'm interested in. Is this force responsible for the rocket not going through the...

    Newton's Third Law and a rocket in space

    Understood. There is a net force in one direction, accelerating the system forward. But, from the rocket's perspective, it is experiencing an equal force in the opposite direction - what does this mean for the rocket? Does it mean the rocket will be unable to go through the object it is pushing...

    Newton's Third Law and a rocket in space

    I am the kind of guy that always needs to return to the horse-and-carriage problem to hone in my understanding of Newton's Third Law. Here's my question. Assume a rocket in space is applying a force to another object of equal mass in space. Now, I understand the object in space is experiencing...

    Limitations in Experimentation?

    I apologize for posting a broken link, but you understood my question. Great analogy. Obviously, the train hitting a bird will not come to a full stop. In the video, a heavier moving cart collides with an immobile, lighter cart. The momentums of the carts are said to transfer, giving the...

    Limitations in Experimentation?

    Why doesn't the higher mass cart stop after hitting the lower mass object? Is this due to an imperfection in setting up the experiment? I was expecting that the equal and opposite force would completely cease the larger mass' motion...
