Angular momentum

principle

A rotating body conserves its angular momentum.

Where it is used

• Gyroscope — is used in. The rotor keeps the direction of its axis.
• Spinning top — is used in. A top is stable while it spins.
• Bicycle — is used in. The spinning wheels and the steering geometry help keep balance.
• Flywheel energy storage — is used in. Rotational energy.
• Spindle — is used in. Spinning the spindle twists the thread.
• Rifling — is used in. Spin stabilizes the bullet.
• Boomerang — is used in. Gyroscopic precession brings the boomerang back.
• Yo-yo — is used in. Rotation.
• Reaction wheel — is used in. Conservation of angular momentum.
• Potter’s wheel — is used in. A heavy disc keeps spinning by inertia.
• Flywheel — is used in. A flywheel stores rotational energy: conserved angular momentum smooths a machine's motion.
