Angular Momentum

Product of rotational inertia and rotational velocity


Law of Conservation of Momentum

An object or syem of objcts will maintain a constant angular momentum unles acted upon by an unbalanced external torque


Lever Arm

The perpendicular distance between an axis an the line of action of a force that tends to produce rotation about an axis


Perturbation

The deviation of an orbiting object from its path around a center of force caused by the action of an additional center of force.


Rotational Velocity

Rotational speed together with a direction for the axis of rotation or revolution


Torque

The rotational analog of force; hte product of froce and lever arm. produce rotational acceleration


InverseSquare Law

A phyical quantity varies as another quantity squared.


Law of Universal Gravitation

For any pair of objects, each object attracts the other with a force that is directly proportional to the product of the masses of the objects, and inveresely proportionall to the square of their distances between their center of masses.


Linear Momentum

Product of mass and velocity of an object.


Rotational Inertia

The reluctance of an object to change its state of rotation, determined by the distribution of the mass of the object and the location of the axis of rotation or revolution


Tangential Velocity

the speed of an object moving along a circular path


Universal Gravitational Constant

The constant G in the equation
6.67 * 10 11 n2 m2/kg2
