re: Pendulum Physics
I humbling day of experimentation. Here is a photo of the rig. I took some video, but some of it didn't turn out. I'll have to set it up and try again. I found that the drop weight on the right comes back up higher when the pendulum starts higher and ends lower. As opposed to the pendulum starting l...

re: Pendulum Physics
Thanks for the discussion guys. This idea is bouncing off of you guys a lot better than it is bouncing of my wife... It kind of hits her with a thud and fall to the floor. Then she trips over it and gets upset with me. haha. I'll have to figure out a series of experiments to get some empirical data....

re: Pendulum Physics
CoAM then says that increasing radius leads to a decrease in speed Increasing the radius does not decrease speed. It decreases rotations per second (or minute). The speed and energy are constant. Ever seen a figure skater spin? They start with arms extended out their sides, twist their body as they...

re: Pendulum Physics
The constant applied force on the beam is not needed in a theoretical frictionless environment. We should assume the beam will continue rotating without adding energy. The illustration above (however confusing it may be), has the axis of the pendulum on the other side of the axis of rotation. The pe...

re: Pendulum Physics
Thanks for the attention. First let us assume no friction in our merry go round. If we add energy to the rotation. The merry go round spins and keeps spinning, this is our kinetic energy. The potential energy is the distance the pendulum on the end of the beam raises up. Is this potential energy free?

re: Pendulum Physics
Nearly a hundred people have seen this post, and no comments. Hmmm. Is this a little too complicated? I guess I am asking if this is overunity. I'll try re-explaining it. 1. Get a horizontal beam that can rotate on a vertical axis. 2. Put a pendulum on the end of the beam so that it can swing out ra...

re: Will JC Ever Publish All His Juicy Wheel Secrets?
The laws of physics will not be broken when a wheel is made public. I took the time to open up a Schaum's Outline and learn some algebra and physics. One thing I found interesting is an interesting discrepancy between linear motion and rotating motion. linear motion( a=acceleration, v=velocity, d=di...

re: PM & reactionless drive
I do believe this would OverUnity. If you have an object with a constant acceleration consuming a constant energy. At some point the object will have separated itself from Earth gaining enough potential energy + the kinetic energy that the two combined would eventually exceed the energy consumed. Fo...

re: Gravity
A slight different thought from my previous post... If energy is acquired from acceleration(gravity), then would it stand to reason that an acceleration engine would weigh less during operation? In correlation, if we added energy to this wheel to make it rotate faster, would it cause the wheel to pr...

re: Gravity
Energy and momentum are not the same. I like to use metric, so I'll explain with that. Kinetic Energy = mass * velocity^2 / 2 Potential Energy = mass * acceleration * distance aka mass * gravity * height Momentum = mass * velocity. velocity = distance / time acceleration = distance / time^2 = veloci...
