Question

The electric pencil sharpener in Mrs. Brown's classroom gets very warm on days when many students need to sharpen their pencils.

Answer 1

Mechanical energy
first the pencil sharpener gets electricity from the plug and wires
that then makes the pencil sharpener move it's motor and well, sharpen pencils
all the kinetic energy from the motor moving releases heat, making the sharpener warm

Answer 2

Answer: Mechanical Energy

Explanation:

According of law of conservation of energy, energy can neither be created nor be destroyed. It can only transformed from one form to another.

When electric sharpener works by using electrical energy, it is being used to drive the blades of the sharpener and is being converted to mechanical energy which is then converted to heat energy and the sharpener gets warm.

Electrical energy is the energy possessed by virtue of motion of electrons.

Mechanical energy is the energy possessed by a body by virtue of its position and motion.

Heat energy is the transfer of thermal energy from hotter body to colder body.
