Answer
Energy in a spinning flywheel is stored as kinetic energy. This is due to the rotational motion of the flywheel, which depends on its mass and the square of its angular velocity.
Step 2
State one way to increase the amount of energy stored in the flywheel.

Answer
One way to increase the amount of energy stored in the flywheel is to increase the speed of spinning. Alternatively, increasing the mass of the flywheel will also contribute to higher energy storage.
