Source sentences:
text: The physics behind a flywheel mean that it needs a large amount of torque to get it rotating, but in turn it also needs a large torque to slow it down, meaning that it conserves angular momentum very effectively.
text: When used in vehicles, flywheels also act as gyroscopes, since their angular momentum is typically of a similar order of magnitude as the forces acting on the moving vehicle.
