Can you define Work as the amount of energy transformed within a system?
In other words, it transfers its kinetic energy to the "outside" particles.
In both these examples, one system "gained" energy while the other "lost" energy. Though the net change is still 0. … There doesn't seem to be any energy transfer occurring. Rather, the kinetic energy of the earth-ball system is being transformed into potential energy. …

Energy of an accelerated charge?
After some time, t, we can calculate the new potential energy of the particle. The difference in potential energy between t = 0 and t = t must be the kinetic energy of the particle at time t. … I was taught that EM waves are "packets of energy." How come in all my EM courses...I never had to account for this loss of energy in the form of EM waves? …

How many degrees of freedom does a spring have?
Here are my thoughts:
Firstly, I like to think of degrees of freedom as places where energy can go. For example, in a gas, energy can be transferred into a particle as kinetic energy. … potential energy. …
