It's not the acceleration itself that increases the energy. It's the force, and only if that force continues to act after the collision...

The thing that makes Einstein's relativity unique is the Second Postulate: Light in a vacuum always moves at the same speed regardless...

I don't understand what you mean by "relative to the speed of light"? We refer to objects, not speeds, when we speak of relative motion...

I was there when the technology for creating video content became available. The possibilities are enticing and the equipment (very)...

Schoedinger did his seminal work when he was at least 38 years of age. Very late in life for a physicist.

Interesting. So the issue of collapse is just an artifact of the nonrelativistic approximation?

Yes, but to the uninitiated, learning about mass involves sorting out its relationship to weight. In medicine and commerce they are...

Yes. Anyone who has ever taught introductory physics has encountered students who have trouble grasping the concept of mass, and sorting...

Okay. The instructions in 1 prompt us to rank the cars, not the relevant property (time) of the car's journeys. Prompting us for a...

If the authors meant rank the fluids that's what they should have written. Not "rank the densities". Density is a property of a fluid...

That's the version that appears in the textbooks. I also assume it's true. You mean that water would be in a state of neutral buoyancy.

That's not worded correctly. It should be asking you to rank the magnitudes of the buoyant forces. Clearly, the densities are not all equal.

You could, for example, have a way of measuring the pressure such that you can identify the location of a high pressure region (a wave...

Yup, I agree. I bungled it up. I was trying to make the statements of the speed of light to that of sound as comparable as possible, but...

I find this comparison confusing: - For sound you talk about "moving relative to the wave". (Whatever that means) - For light you talk...
