 * Definition:

Circular Motion
Movement of an object at constant speed around a circle with fixed radius __**Tangential Speed:**__ Speed along a circular path
 * __Axis:__** Straight line around which rotation takes place
 * __Rotation:__** Object turns around an internal axis
 * __Revolution:__** Turns around an external axis
 * __Rotational Speed__**: Number of unit of time
 * __Linear Speed:__** Distance/Time
 * __Centripetal Force__**: Force that cause an object to follow a circular path
 * __Centripetal Acceleration__**: Always points towards the center of the circular motion

__**Tangential Speed:D**__istinguished from a normal force, which acts at right angles to the tangent and changes the direction of the motion without changing the velocity move in a circular path; a force towards the center.
 * Explanations:
 * __Axis:__**line or objects that hold something that is moving.
 * __Rotations:__**a object that is moving.
 * __Revolution:__** opposite direction in where is going.
 * __Rotational Speed:__** when you time something that is moving from start to finish.
 * __Linear Speed:__** the distance where the object is at**__.__**
 * __Centripetal Force:__** Centripetal force is the name given to the force which makes an object
 * __Centripetal Acceleration: F__**or example, it is used to solve problems about rollercoasters or about objects moving on the end of a string.

=Centripetal Force= Any motion in a curved path represents accelerated motion, and requires a [|force] directed toward the center of curvature of the path. This force is called the centripetal force which means "center seeking" force. The force has the magnitude

Basic Formula
We’ll start with the basic force formula, and add in the centripetal acceleration formula we have from [|Lesson 28]. Original Formulas New formula A centrifuge You might have seen movies with an astronaut in training spinning around and around in this big machine to get ready for their flight. The device is called a //**centrifuge**//, like the one pictured at right (click on it to go to the Nasa website for the [|Center for Gravitational Biology Research]). Let’s look at the forces on a 100 kg person’s body, and try to relate it back to regular Earth gravity (one “gee” = 9.81m/s2). Keep in mind that just standing on the ground the person in this example would normally weigh (//Fg = mg//) 9.81e2N. What is the centripetal force acting on this 100kg person if he is spun around in a 8.80m circle at… =Coulomb's law=
 * It is like Newton's law of gravity. But unlike gravity, Electric forces can be attractive or repulsive. Discovered by French Scientist Charles Coulomb in the 18th Century.
