急...急..急..分別可在??? K.E & P.E

POTENTIAL ENERGY 係勢能
多數指地心吸力果D
勢能
由上到下
愈高愈多
for example:
POTENTIAL ENERGY
有個波係山上跌落去山下
(POTENTIAL ENERGY令個波跌落去)
KINETIC ENERGY 係動能
即係d野移動(但不包括地心吸力)
for example:
你自已係度移動身體
你移動用左 KINETIC ENERGY


分別有個波係山上跌落去山下
係
POTENTIAL ENERGY
(個波係山上"儲"左dPOTENTIAL ENERGY)
轉做
KINETIC ENERGY
(個波係山上"儲"左既POTENTIAL ENERGY
變左KINETIC ENERGY跌落去,d POTENTIAL ENERGY"用左")
PS energy 係5會多左/少左,只會轉左

Potential energy is the energy possessed by a body by virtual of its position in a field (gravitational or electrostatic or the like). Potential energy could also be applied to energy possessed by objects under deformation(elastic potential energy), e.g. a compressed spring.

Kinetic energy is the energy possessed by a body by virtual of its motion. Examples are plenty, a moving vehicle, a flying plane, a falling apples... etc.
