THE PRINCIPLE OF ENERGY CONVERSION
The phenomenon of one type of mechanical
energy converting into another can be observed on
the apparatus
in the picture. We tie a string around the axis of
the disc and lift it up. The disc, while in the lifted
position, has some potential energy. If to let go
of the disc, it would start to descend while rotating.
As the disc descends, the potential energy decreases
and the kinetic energy increases. At the end of its
descent, the disc has enough kinetic energy to almost
return to its original (starting) position. (A part
of the energy is used to counter inertia, and therefore
the disc can't fully regain its starting position.)
After ascending, the disc once again falls, and once
again ascends. In this example, as the disc descends,
its potential energy converts into kinetic, and vice
versa during ascent. Try to explain the same principle
on the second animation.
