The law of conservation of momentum is WRONG practically tried.

In summary: Though the momentum from the ball will be completely transfered, since the body is very heavy, the momentum will be more by virtue of mass...since K.E has an exponential square relationship with velocity, we can say that despite all the momentum getting transferred to the heavy body, most of the energy is still left...this is seen in the form of a recoil on the ball.Based on the principle that when you propel a mass (suppose a ball) on a heavy body and make it hit the heavy body, the impulse that was given to the ball will be transferred to the heavy body, I developed a propulsion system which has

I don't know if there is a language barrier here and some of what you are saying is lost in translation. BUt most of what you have said doesn't seem to form a coherent idea.

It appears that you are saying you have invented a new propulsion system and have come to the conclusion that the law of conservation of momentum is wrong as a result. No matter what you think you've done you haven't broken the laws of physics, and if your system isn't working, its a flaw with the system not the law.

Now unfortunately, as I'm having trouble trying to picture just what the hell you are talking about its impossible to find the flaws in the thinking.

AND EDIT: What the hell is it with people thinking magnets are magical devices that can be considered as not interacting?

The invention has lots of potency.

I made an arrangement...actually in my invention there are 2 predefined arrangements which work in cycles...so there is a very powerful net propulsion using this principle, so 80-90% elasticity will work very well.

Practically...yeah I agree that I absolutely do not have resource...the collision was not even close to elastic.

So you mean to say, the invention works?...it should work...this is one of its kind, this is an ideal propulsion system.
No, the 'invention' has zero potency.

As far as I can tell your set-up is analogous to the standard problem of a person walking on a canoe. Since there is no net external force on the system (person boat or ball boat in your case) the centre of mass of the system remains stationary. Now, if the person starts to walk along the canoe (or your ball begins to roll) the boat will indeed begin to move in the opposite direction (conservation of momentum). Now, if that person stops (or your ball hits the wall), then the boat must also stop. If the person then walks the other way (or the ball rebounds), then the boat will move in the opposite direction.

The net result is that your boat will go nowhere.

It should work? Nope. I take it that you verified that it doesn't, correct? (Or is this just an experiment done "on paper"? :wink:)

This is just an elaborate mechanism for converting chemical energy (from your muscles when you threw the ball) into random thermal motion. Not a means of propulsion.

No if it does not work, the law of conservation of momentum is wrong.

And it apparently is not working.



This is not my first invention you know...so I know what sort of difficulties you face, what a company wants etc...

:smile:

I'm using a ball and magnet for a reason.

The ball STOPS on the boat...if you say there's no propulsion...where did the energy go?

Since there is no net external force on the system (person boat or ball boat in your case) the centre of mass of the system remains stationary.

There is absolutely no law which adds this hindrance...its a misconception.

And if it's not working law of conservation of energy or momentum is wrong!...it's clear!

Now, if the person starts to walk along the canoe (or your ball begins to roll) the boat will indeed begin to move in the opposite direction (conservation of momentum). Now, if that person stops (or your ball hits the wall), then the boat must also stop. If the person then walks the other way (or the ball rebounds), then the boat will move in the opposite direction.

There's really a lot more to this.

I did it practically...no it did not work and I want to diagnose why.

If it does not work...the laws are wrong and it did not work.

Thermal?...are you kidding me, we're considering elastic here and you said thermal?

Till now absolutely no one has proved in the invention wrong, yet they say it won't work...what is this?

Random thermal motion.

Momentum is conserved.

Thermal?...are you kidding me, we're considering elastic here and you said thermal?
:rolleyes: If you stop the ball, it's not "elastic".

Since the rest of us understand conservation of momentum and energy, the burden is on you to prove them wrong. But don't bother doing it here.

Playtime's over. This thread is done.

Wow! I'm really impressed. :rolleyes:

It doesn't matter what you used. The ball stops and ergo the boat must also stop due to conservation of momentum, is this not what you observed?
dE_logics said:

The energy didn't go anywhere, the net amount of energy of the system (you, ball and boat) remained constant.
dE_logics said:

Yes there is, it's called conservation of momentum.
dE_logics said:

Now you're just being a crank.
dE_logics said:

No there's not, it's really quite simple. That is, until you managed to over complicate things with your inadequate explanations.
dE_logics said:

Perhaps heat in your muscles?
dE_logics said:

Unless I'm very much mistaken, you have done an experiment that proves it doesn't work. Haven't you?
