Energy is the conserved quantity associated to time-translation invariance and represents the work a system is capable of doing. Use this tag for questions about energy, and consider adding the [energy-conservation] tag if it is specifically about its conservation.

Question about distillation
Higher boiling point means that after the system changes into gaseous state (most probably), it radiates energy faster that the substance with the lower melting point. … If yes then explain why does the substance with higher boiling point radiate energy faster?
If not then please mention the right mechanism . …

Relationship between impact crater properties and kinetic energy? [duplicate]
So is kinetic energy inversely (squared) proportional to the quantity of clay displaced or is it proportional to the depth to which the ball will go ? … i am not asking about diameter and kinetic energy relationships , i am just askin about a derivation for the depth and displaced amount of material relationship with kinetic energy of some object. …

Why doesn't frequency of a sound wave reduce with time?
I understand how energy depends on amplitude as this source says but this source mentions that the energy of a sound wave depends (maybe "also on") on frequency of the sound wave. … If energy of a wave depends on its frequency then won't that frequency reduce by a significant amount as the sound wave travels (the energy converts into other forms)? …

Conventions and realities of kinetic energy?
I am having doubts regarding why $1/2$ is present in kinetic energy and if this is conventional why cant we say potential energy is $2mgh$ and kinetic energy $mv^2$. … In addition can someone please elaborate Ron Maimon's answer, especially what does he mean by energy mixing with momentum? …

Factors that affect energy of a sound wave?
Putting a lot of energy into a transverse pulse will not effect the wavelength, the frequency or the speed of the pulse. … The energy imparted to a pulse will only affect the amplitude of that pulse.why is it like that? …
