re: energy producing experiments

[Cloxxki]

Anybody can do a mathy video but experiments tell the truth.

Increasing the length of your string does not change the momentum in the tiniest bit. Law of Levers proves angular momentum is false. Repeat the following experiment and you will see.

A pulley could have two radii: one radius at 2 cm and another at 20 cm. 1 kg suspended from the 20 cm radius balances 10 kg suspended from the 2 cm radius; this means that the sides have equal angular accelerated. An extra mass of 10 kg can accelerate 2 kg (one kg on each side) at the 20 cm radius just as easily as it would accelerate 20 kg (ten kg on each side) at the 2 cm radius.

This pulley can be used in an Atwood's machine and you could place 10 kg on both sides of the 2 cm radius or you could place 1 kg on both sides at the 20 cm radius. These two arrangements would have the same angular acceleration.

An extra 10 kg accelerating another 20 kg all at the 2 cm position would be the same angular acceleration as an extra 10 kg at the 2 cm accelerating 2 kg at the 20 cm position.  I have done this type of experimentally many times.

Ten kilograms accelerating another 20 kg, all at the 2 cm position, would have a linear arc acceleration of 3.27 m/sec². After the suspended 10 kg has dropped 1 m all three 10 kg masses would be moving; d = ½ v²/a; 1 m = ½ v²/9.81 m/sec² = 2.557 m/sec. The angular acceleration would be the same for the 2 kg at the 20 cm position. So the two 1 kg masses at 20 cm radius would be moving 25.57 m/sec.

The energy input here is 10 kg dropped one meter: 9.81 N/ kg * 10 kg * 1 m = 98.1 joules.  A joule is a Nm

The energy of 2 kg moving 25.57 m/sec is ½ mv² = 654 joules. The 10 kg moving down at 2.557 m/sec is 32.7 joules. This is a total energy of 686.7 joules; 700% of the original energy used to make the motion.

700% of the original input energy.

There is a means of transferring the motion from the falling 10 kg and the spinning mass of the pulley for 1500%

"25.57 m/sec"
Is that not a 10x error?

The same Force will accelerate (10 kg at 2 cm) or (1 kg at 20 cm) at the same rotational rate.

Any force will be producing 10 times more energy at the (1 kg at 20 cm) location.

9.81 N at 2 cm will accelerate (10 kg at 2 cm) to .981 m/sec in one second.

The (1 kg at 20 cm) will have the same rate of rotation; but it is ten time further from the axis of rotation, so it will be moving ten times as fast. The 1 kg will be moving 9.81 m/sec.

½ * 10 kg * .981 m/sec * .981 m/sec = 4.81 joules

½ * 1 kg * 9.81 m/sec * 9.81 m/sec = 48.1 joules

Just about any wheel will prove this correct. I have used cartwheels, scrap wheels from a band saw; two circles of plywood glued together, a plywood circle with just a shaft through the center. You could do the experiment with a bicycle turned upside down.

The black wheel in the Delburt Phend youtube is proving something else; can you guess what it is?

And how much energy is needed to produce (10 kg moving .981 m/sec at 2 cm)?
Well, an Atwood's with 4.5 kg on the left and 5.5 kg on the right would produce a 10 kg mass moving .981 after a drop of .4905 m for the extra 1 kg on the right.

That energy is    Let's use potential energy Nm   1 kg * 9.81 N/ kg * .4905 m = 4.81 joules. 

So, it takes 4.81 joules to produce 48.1 joules.

No, it is not a mistake; and yes, it is worth trillions of dollars.

Ok Dilbert. Let's walk down your path.


Experiment, right?


Get you something consistent; and repeatable
A hitting force: to punch your tetherball.


Dont have a tetherball? Thats ok attach any mass to a string


And hit it with consistent force such that it wraps around the post.
Now stand there; let the ball hit you.


Change the length of the string
Do it again


And see for yourself how or how does not the length of the string change the rotation velocity.

[sm0ky2]

Spin the whirly go round, now move yourself from near the center towards the outer rim, and back again.


Understand the difference; feel it pulling on yourself.
Still not convinced? Let go




If the length of the string didnt matter, than the tetherball would hit the person with the same force it was hit with.
But the reality of the situation is a small child can knock out a full grown man with one of those things.

[sm0ky2]

Conservation of momentum does not violate conservation of energy.
Both will always hold true.
In fact one can be derived from the other


lets take a Newton's Cradle; but make it cylindrical so the last ball swings around and hits the first


Or more accurately, place a larger ball in the center of the rest of the balls.
