Can energy double?
If an iron ball weighting 10kg is placed on the edge of a table and let it drop pulling a toy car of the same weight from the top of the table, the frictional resistance of the car is 2kg. When the ball is about to reach the ground, the ball and the car both have the kinetic energy (10kg×10m-20)(20 by friction consumption), thus 100( potential energy) = 160(kinetic energy).
During the whole process, the ball travels vertically from the table top to the ground, while the car travels horizontally from one end of the table top to the other. If the car is attached to a generator set on the edge of the table, the colliding force will makes it work. And the same is true with the ball.

so how would you close the loop here? how will this self reset to repeat its process? you're saying the generator will provide enough energy to reset the system?

160-100(reset)=60(net gained)

is this something you came up with or you found this?

this is like an electro-kinetic-gravity machine type of thing.

The car is the same weight of the ball? Will the ball really fall?

yes the ball would fall but not at free fall speed. i can be wrong though.

Hmmm... Maybe the ball falls, but at slow speed, so the kinetic energy will be far less than the kinetic energy of the ball falling without having to pull the car.

No, energy won't double.

Experiment:
 
Set a generator and an iron ball weighing 1kg at one edge of a table.
Connect the ball with a toy car weighing 1kg placed at the opposite end of the table top. The distance between the ball and the car is 10m.
Drop the ball. Pulled by the ball, the car travels from one end of the table top to the other, colliding with the generator to produce electricity.
At the same time, the colliding force of the iron ball makes another generator set on the ground produce electricity, with approximately a half potion of which the ball would be lifted and the car pulled back. Thus the device would circulate on end.
Friction=0.2kg,  g=10 m/s2。
The accelerating speed of the iron ball and the car is:
F=ma, F=G-f=1×10-2=8N, a=F/m=8/1=8(m/s2)
The end speed of the iron ball and the car is:
Vt2=2as=2×8×10=160, Vt =40(m/s)
The kinetic energy of the iron ball and the car is:
Ek=1/2mvt2 =1/2×1×160=80(J)
The energy consumed to set the iron ball back in place.
The energy consumed to set the car back in place is negligible.(At most, E=fs=2×10=20J)
Ep=GH=10×10=100(J)
The energy gained:
E=80×2-100=60(J)。

i thought this system only had 1 generator and not 2.

anyone going to try this experiment?

according to the graph what generator would you recommend to build this in real life?
how would you build this in real life using off the shelf parts?

For example: you modify a generator and connect it to the rear wheel of a bike, when the ball hits the pedal of the bike, the generator works.

Hi Zhang,

How much work should be done to lift the ball up to the same 10m height, after it fell down? Use your 1kg ball weight like in your last calculation.

Thanks,  Gyula
