1. I cannot find.
2.
kinetic energy- 動能- When an object is moving, it has kinetic energy.
eg. a running horse, a flying plane...

potential energy-勢能- It is a form of stored energy. An object in a stretched(伸展) or compressed(壓縮) state may have potential energy.
eg. a stretched bowstring(弓弦), a compressed spring(彈簧)

Others: Heat energy(熱能)
Light energy(光能)
Sound energy(聲能)
Electrical energy(電能)
