Hi to all ...
hope you all doing good and continue on the research ;)
So here are two questions am thinking about but am not sure of answer.
1. Just hypothetically, if you were able to slow down the "time" when the weight fall or raise up. Could it help to find prime mover?
2. It is known that slower moving object cant give its energy to faster moving to move it faster. So what if you could?. Hope am clear with this one.
Those are just theory questions which are going thru my mind for a moment and i still dont see the answer, and am bit short on time for searching coz of lot of work. I know here are some really smart guys that could help me to answer those questions instantly.
Thanks.

re: Couple of questions
If you believe in conservation of energy:
1. If you let a weight freefall, like a pendulum, it will swing almost to the height it was dropped from. If you slow the fall, capture the energy and use that to accelerate a weight upwards, friction will cause the potential energy of the second weight to also be less than you started with.
2. You have two weights travelling at the same speed. As above, you slow one weight and give the energy to accelerate the other. As the first weight comes to a stop, the second weight is now only travelling at 1.4 times its original speed, not the 2 times you were hoping for. Why?

Thanks for the answer Tarsier79 but you missed the both questions, sorry.
1. I was just hypothetically asking about slowing the time ..not by ordinary breaking and storing energy of the falling weight. Just if fall could be slowed down like one weight is falling in slow motion ...
2. Well also here i didnt meant i have two the same speed moving objects ...am only talking about slow and fast moving object ... and if slow one could transfer its energy to faster one in that way the faster one will accelerate. If that could be achieved what it could mean in search for a prime mover.
Thanks.

re: Couple of questions
Did I misunderstand the question, or did you misunderstand my answer? Perhaps it is a little of both?Thanks for the answer Tarsier79 but you missed the both questions, sorry.
1. How does slowing falling help? Do you mean with a parachute? Are you talking about time dialation? PE=mass x gravity x height. Where does time come into that equation?
2. "Well also here i didnt meant i have two the same speed moving objects"... as you take speed from one, it becomes a slower moving object, and youcontinue to transfer its energy to the faster moving object until the slower moves at a speed of 0.
So the answer to both questions IMO is: No, neither is an advantage to a working wheel.

as for transferring velocity the answer is simple. KE is v2 but momentum is a straight line so transferring all the velocity to one mass is a gain proportional to v2 -- in other words well worth doing
Not knowing is not the problem. It is the knowing of what just isn't so.
It is our responsibilities, not ourselves,that we should take seriously.

Imagine a pendulum that reaches 8 feet per second
It collides with a mass at the peak of its velocity
assume the pendulum is much more massive than the mass it collides with
assume the collision is elastic
the pendulum sees a 1/4 second equivalent impulse as the mass is brought to 8 fps
it sees a second 1/4 second impulse as the elastic portion of the collision accelerates the mass away at 16fps
at the same time 2 equivalent masses are launched in the opposite direction from the pendulum
at 1g acceleration takes 1 foot to achieve 8 fps and takes 1/4 second
there were 2 to match the impulses of the collision - they restore the pendulums velocity
so you get 4 feet kE for 2 one foot investment

Gday Kirk,
Have you finished your POP build? Untill there is physical proof, I am doubtfull of the calculated energy gains in conserving momentum.
