How can an object at rest have energy?

It can have potential energy due to its location.How can an object at rest have energy?
Kinetic energy.How can an object at rest have energy?
If you're constantly in motion, how can you possibly have any energy? Boy, just *thinking* about it makes me tired. Excuse me while I sit down for a while.





An object at rest has *potential* energy. A stick of dynamite at rest has a lot of energy. So does a gallon of gasoline.





But if you have a big rock on top of the roof, it has energy, too. Just tap it, and it comes flying down, picking up speed, until it hits your foot and you hop around on the other foot going ';Ouch, ouch, ouch!';
Yes, an object at rest has potential energy.
It breathes. and not like we do.
Objects at rest have Potential energy. Look up E=Mc2





You sitting at rest have the potential to move - ';grubs up'; !


A poolball has the potential to move - when I whack it with a cue.


etc etc
Everyone speaking of potential energy has completely neglected the concept of ';internal energy';. Unless a substance is at ABSOLUTE ZERO, the atoms and molecules within it are moving. Heat energy, the enthalpy of the substance, is always a factor in determining the total energy of an object. Electrons move around the nucleus, sub-atomic particles vibrate, quarks spin. And, of course, the substance itself has an equivalent in energy if all its matter were to be converted to energy.





So, yes, an object at rest has plenty of energy. Chemical energy, thermal energy, atomic energy, potential energy... the list goes on. Kinetic energy in the sense of classic physics is only one measurement.
