The graph shows the efficiency of three types of light bulbs: incandescent, fluorescent, and LED. What can you conclude about the energy efficiency of the light bulbs?
Incandescent light bulbs use less energy than either LED or fluorescent bulbs.
Fluorescent light bulbs are the most energy efficient since their light and heat energy are most equal.
Incandescent light bulbs rely on heat energy to process light, increasing the light output while decreasing the heat output.
LED light bulbs provide more light energy while producing less heat energy, making them the most energy-efficient of the three types of bulbs.

Airplane 2 has less potential energy than Airplane 1.
The two airplanes have the same potential energy, but a different kinetic energy.
Airplane 1 has more kinetic energy than Airplane 2.
