Why is gravitational potential energy of a body always negative of the work done on a body? Explain about gravitational and elastic potential energy. What is the difference between potential energy and gravitational potential energy? What is the difference between gravitational potential ...
If the potential at infinity is {eq}\frac{-GM}{r}{/eq}. Then what is the potential at the surface of the earth? Please explain the approach. Shifting The Potential Energy Scale The gravitational potential energy of a system of mass...
4 (a) A power station uses wind energy to generate electricity.State and explain whether this method of generating electricity is renewable.statement ..explanation[2](b)State two energy resources that do not have the Sun as their source.1...2...[2](c) For each energy resource, state th...
1) We should not, as the current explanation does, say that the particles gain energy. The Law of Conservation of Energy strictly demands that we say, instead, that they convert gravitational potential energy into kinetic energy, but only as much as the resulting pressure, resisting gravitational...
(In effect, we store electricity as gravitational potential energy, which we can do indefinitely, and turn it back to electricity when it suits us.) Photo: How pumped storage works: When there's lots of cheap electricity about (at night or when the wind is blowing), water is pumped up ...
Summing up, in the JF(E), where energy is conserved but energy-momentum is not, photons are the means of measuring length, time and mass. Proper mass increases with gravitational potential energy an...
When a spring is compressed, the energy changes from kinetic to potential. Which best describes what is causing this change: work, power, gravitational energy, or chemical energy? For adiabatic process \Delta U = nC_v \Delta T , ...
The curvature will be custom-tailored for every particle that interacts with the gravitational "field", No. The curvature is caused by the stress-energy tensor, as I said above. The stress-energy tensor is a property of the object that is the source of the field, not the object that is...
Cite the three major differences between gravitational and electrical forces. What is the discrepancy formula in physics? Define Poisson's ratio. What is mean by gravitational intensity? Explain the inverse relationship between kinetic energy and potential energy. (Sentence starter clues: If the ...
We treat it as though it were a constant, but the strength with which Earth's gravitational force pulls on objects varies across the surface of our planet: it's greatest the closer you are to the center of Earth, so it gets slightly less as you climb mountains and slightly more as you...
