Solar Light

APES-XEPKDG

Solar yard lights have become common. Explain the various forms of energy demonstrated as sunlight is converted to electricity and eventually light from the small LED bulb in a yard light.

A

The sun releases light energy, a form of kinetic energy.

B

Kinetic energy (in the form of light) from the sun is converted into electrical energy (also kinetic).

C

Light energy (kinetic) is converted to electrical energy (kinetic) which is then converted to light energy (kinetic).

D

The amount of kinetic energy that hits the solar light panel is less than the amount of kinetic energy released by the solar light.

E

Light energy (kinetic) is converted to electrical energy (potential) which is then converted to light energy (kinetic).
