Title

Physics- Circular motion–Revolutions or an object moving around in a circular motion

• The Earth rotating around the sun

- Centripetal force–The force needed to keep an object moving in a circle

- Centripetal acceleration–The acceleration that is always directed toward the center of a circle

- Rotational motion–Spinning

- Angular displacement–How far in angles something moves

- Angular velocity–The speed at which you rotate

- Angular acceleration–Change in rotational speed

- Torque–A force that causes you to spin

- Rotational inertia–The tendency for an object to resist rotation

- Rotational kinetic energy–Energy of rotational motion

- Angular momentum–The amount of umph a spinning object has

- The Law of Conservation of Angular Momentum–Higher inertia, lower speed
