Describe angular momentum and linear momentum. Include two ways that they are alike and two ways that they are different. Be sure to discuss how mass affects both angular and linear momentum.

Angular momentum is the product of a moment of inertia and its angular velocity. It is defined to an object that is rotating.

Linear momentum is the product of a mass and its velocity where the velocity and the momentum are going to the same direction.

Angular momentum is normal to the motion while Linear momentum is parallel with the motion. Torque is needed to change an objects angular momentum while a force is needed to change and objects linear momentum.

Both angular and linear momentum depends on the mass and the velocity of the object.

Inertia is directly proportional to mass, thus when mass is increase with the same velocity, momentum increases. When mass is decreased, momentum also decreases.
