A fan is plugged into the wall. The electrical energy from the outlet travels into the motor of the fan and causes the blades of the fan to spin. The blades cause the

molecules of air to begin to move, creating a cooling breeze. What type of energy is demonstrated by both the blades of the fan and the air molecules?

a. thermal energy from the heat of the motor
b. electric energy from the current and the static it creates
c. potential energy based on position
d. kinetic energy of motion

Step-by-step explanation:

The type of energy demonstrated by both the blades of the fan and the air molecules is d. kinetic energy of motion.

When the motor of the fan receives electrical energy, it converts it into kinetic energy, which is then transferred to the blades of the fan. The blades, in turn, convert this kinetic energy into the motion of air molecules, which also possess kinetic energy. This motion of air molecules creates a cooling breeze, which is a form of kinetic energy. Therefore, both the blades of the fan and the air molecules are demonstrating kinetic energy.
