The root of 8*19^10 cm is 2,828E+05 It is some years ago. probably everybody knows already. I just want to be sure about this. It does not match any of the given values.

Wow. Thank you for your persistence.

It seems to me that in the animated video at 1.13 min. the worldline is expanding (at least the cilinder changes to an expanding model). Is that correct? If yes:What does this expanding mean? Is this the bending space? What does it really mean?

It seems to me, that your question is headed for the equality of inertial and gravitational mass. In par. 20 of the general Relativity Theory Einstein describes the identity of slow and heavy mass as an argument for the general principle. Einstein describes thereby an idea that you can imagine...

OK. It can be closed.

Most important is for me to know that a Watt means: a Watt for an hour. That makes me understand, that the energy is much less than I did count on. Thanks again. Sorry for wasting your time.

Russ: The glass breaks at 24.50. I saw other videos of the same demonstration with Walter Lewis and it really breaks. The force is the combined force of the push by Walter Lewis plus de gravitational kinetic energy. The gravitational energy alone is also painful strong as you would feel if you...

BvU: I indeed made a mistake in Watt= J/s I controlled the calc in Excel and the result is: 558 J (not 345: OK?) The period is indeed 2,8 sec and not 1 sec. I want the pendulum be pushed back from the highest point. See Walter Lewis in this video. From 25 minutes. I want to put a permanent...

I would like to make a pendulum go on moving by a permanent magnet that pushes the pendulum back with a force that is big enough to make it swing back with the same height. Can anyone tell me how much energy could be generated by a pendulum with height is 2 meter and 60 kg, swinging 90 degrees...

Each speed is relative to the center of the big mass: Earth orbiting the center of our solar system (the sun), sun orbiting the center of the galaxy. It's just measured by measuring the orbit and the time it takes for one orbit. In fact we take that center as the inertial system from witch we...

The speed of the Earth around the sun is about 70000 km per hour. All planets follow the sun in her circumambulation around the centre of our galaxy with at a speed of about 800.000 km per hour. Keep in mind that our planets with moons and rings (like Saturns rings) and also the Kuiperbelt and...
