physics phenomenon in daily life?

Question

can you tell me where all physics applies in daily life....such as in radios cars cameras etc... like if radio then how does electricity become sound

Answer 1

I think physics could be applied anywhere. All the electronic and mechanical devices use different components discovered using physics. Even the electron, proton inside an atom work according to the laws of physics. However, we don't know all the laws of physics yet to explain many phenomenon of nature like black holes, dark energy, dark matter, pre-big bang etc.

Answer 2

Physics in everyday life is about the way energies are converted from one type to another. There is a continuous unbroken link as one thing causes another and that in turn causes something else. An important thing to keep in mind is that energy can’t be created or destroyed, you have to look for where it comes from and where it goes to at each stage.



In your example the signal hits the aerial as electromagnetic waves and are amplified to produce a strong electrical current oscillating the same as the incoming wave, that electrical energy flows through the coil of a speaker that is suspended in a magnetic field and causes it to vibrate the same as the oscillations in that electrical energy fed to it and those vibrations cause the air in front of the paper sheet stuck to the coil to vibrate and move away as sound.



There was a documentary once where skid marks on the road seemed to describe exactly what happened in an accident but when the forces, masses and speeds were worked out it turned out to be completely different. Physics applies everywhere nad can give you a useful edge if you study it.

Answer 3

there are many amplification in a radio and there electricity is converted into sound energy and in cameras it is converted into light energy...

Answer 4

sound gnomes
