Source sentences:
text: A flywheel is a mechanical device specifically designed to efficiently store rotational energy (kinetic energy), which is proportional to the square of its rotational speed and its mass.
text: Flywheels resist changes in rotational speed by their moment of inertia and in order to change a flywheel's stored energy (without changing its mass) its rotational speed must be increased or decreased.
text: The momentum of the flywheel causes it to not change its rotational speed easily.
text: Flywheels resist changes in their rotational speed by their momentum of inertia.
text: The momentum of the flywheel causes it to not change its rotational speed easily.
text: Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a fluctuating torque is exerted on it by its power source such as a piston-based (reciprocating) engine, or when the load placed on it is intermittent (such as a piston pump).
