Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the energy storage formula?E = ½ Iω²
2. What is the moment of inertia (i)?Dependent on mass and its distribution relative to the axis of rotation
3. How does a flywheel store energy?The energy is stored in the wheel’s spinning motion, depending on how heavy it is and how fast it spins. The faster it spins, the more energy it keeps.
4. Why do factories use flywheels?Flywheels smooth out the power from engines, making machines run more smoothly and protecting parts from sudden jolts.

Conservation of Angular Momentum: A fundamental physics principle stating that the total angular momentum of a system remains constant if no external torque is applied.
Moment of Inertia: A scalar quantity representing an object's resistance to changes in its rotational velocity.
