Terragravitic Induction

Given enough input energy you can achieve many great things.

Here is the inertial propulsion experiment using an oblique pendulum on a cart that I mentioned had similar results IINM to your experiments Frank .. you might be interested in the comparison after seeing the video ..

Very nice build.
You obviously have the skills to build a trolley without having to resort to meccano.
All you need in addition is a decent gyroscope. :-)

The vid is 15 years old, and not made by me lol ..

[Senax]

LOL.
Sorry about that.
My dinner must have been getting cold so I didn't get further than looking at the video.
It was probably interrupted by one of those damned videos on how to reduce belly fat.

In the video Fletcher, is there a way to improve the impact of the rolling weight? If the weight landed on a padded surface or on a spring, would that have increased the travel distance?

If the weight landed on a padded surface or on a spring, would that have increased the travel distance?

Let's assume air frictions are about the same for both the rolling ball experiment and the oblique pendulum experiment .. when he lets the ball roll down the slope we are looking at classic dissipative energy losses - the ball has rolling ( kinetic ) frictions which eat up some of its PE so that its KE is slightly less than the PE it has lost - then it collides with the end wall of the cart - both the ball and the cart wall will deform slightly and this this is another dissipative energy loss - usually about 50% of KE is lost in collisions using ordinary materials ( this has to do with the Coefficient of Restitution COR / Elasticity of the materials ) ..

If we place a padded surface on the wall it will deform a lot and we will lose maximum KE, so the cart will move forward only once and stop - if we put a spring in there it would give back most of the KE it receives on impact ( but not all as there is no perfect spring ( rubber and steel have an Elasticity of about 0.95 ) ) pushing the ball back up the slope a short ways - so the result would be a series of short forward 'hops' until it stops ..

The oblique pendulum experiment does not have any rolling frictions ( it does have pivot frictions ) , and there are zero dissipative energy losses to collisions because there aren't any - so the act of the pendulum swinging uses its inertia to move the cart forward, and each swing it loses a little PE and KE until it dampens down and stops - but the cart hops down the track until the pendulums inertial changes cease .. that's why it is called inertial propulsion ( as long as you restore the pendulum swing ) ..

In short the oblique swinging pendulum is about the most efficient way to convert PE to distance traveled by the cart because it has few energy losses .N.b> this is off the top of my head because I haven't looked at the video in years, and just found it and posted it for Frank to consider alongside his experiments with what I consider is inertial propulsion from his gyro experiment ..

Hope that helps, and no I haven't done the experiments ..

Imo milkovick is comparing apples and oranges at the end of the weights gpe drops.

Maybe you should teach it about the Blackbird (Down Wind Faster Than The Wind vehicle) heading directly into Wind at ground speed 1.8 times Wind Speed. That was always the proof that lift force (thrust) was far greater than drag forces and could be turned into mechanical energy lol.

A good example of earth reaction energy.

An easier one to understand is the Ventomobile which heads directly into the wind.
Part of the wind energy is directed to the wheels which drive it into the wind.
This, of course, increases the relative wind speed which provides even more energy
to the wheels until and equilibrium is reached between wind speed and ground speed.

You were faster off the mark than I on the Blackbird. ;-)

The interesting thing about the Blackbird is that the wind is at right angles to the trolley.
In the case of Edwin's Trolley the Gravitational "Wind" is also at right angles.
(I know that the idea of gravity being viewed as a wind isn't popular with some members
but if its good enough for John (and Newton) it should be good enough for us)

The interesting thing about the Blackbird is that the wind is at right angles to the trolley.

Is it? The Blackbird is DWFTTW. So the wind is blowing with the blackbird, but at a slower pace.

Down Wind Faster Than The Wind

Thanks for correcting that.
I must have been thinking of yachts where the boat can travel virtually at right angles to the wind.
In the case of a yacht the "earth" reaction energy is, of course, that of the lowered keel pressing against the water on the downwind side.

Thanks again.
