Newton's third law is all about momentum. It amounts to a statement that momentum is conserved. Newton's third law has less to do with...

I will say this though: Unfortunately that sounds like exactly what you fear it is. That's what you are going to get most of the time...

Old thread, but in the US "Certified Organic" is an FDA/government certification. So complaints about bad government regulation as a...

Not sure what Newton III has to do with energy. Please elaborate. Thermal energy is just disordered kinetic energy. Can you be more...

I have no idea how to parse this run-on sentence. What is your question? That's a statement about forces, not energy. Different from...

Given the fire risk of lithium, there is little reason to go cheap.

OK, I guess I'm only buying name brand batteries now. Lumafield makes CT scanners for industrial engineering and production testing...

I don't think anyone is saying it can't happen.

If you google "optimal placement wind turbine hill" or similar, you will find more information on exploiting obstacles to improve wind...

I can see how, following cavity collapse, there can be a negative pressure transient of 20MPa, but that would be measured relative to...

Agreed. I think that in certain specific/limited/contrived circumstances it is likely to be possible for a given small wind turbine to...

There are other things going on. Please try to understand Bernoulli's equation, which gives the trade-off between pressure and velocity.

The streamline figures in post 27 can be somewhat deceiving at first glance. The streamline figure spacing is shown compressed, rather...

Yes. So that is where the velocity can come from -- decreased pressure. This just means that the random directional movement of atoms...

Right. And these are forms of energy: kinetic energy increases, pressure energy decreases. That's the energy that gets traded from one...
