|
Rotary Motion
|
|
|
Angle formed by radius along the ark and the other radius; 57.3 degrees; 6.28 of them in a circle
|
Radian
|
|
|
The straight line around which an object may rotate or revolve
|
Axis
|
|
|
An apparent outward force on a rotating or revolving body. It is fictitious to the sense that it is not part of an interaction but is due to the tendency of a moving body to move in a straight line.
|
Centrifugal Force
|
|
|
The path distance moved per unit of time. Also called simply speed.
|
Linear speed
|
|
|
Motion of an object turning around an axis outside an object.
|
Revolution
|
|
|
The spinnning motion that takes place when an object rotates about an axis located within the object.
|
Rotation
|
|
|
The number of rotations or revolutions per unit of time; often measured in rotations or revolutions per second or per minute
|
ratational speed
|
|
|
The speed of an object moving along a circular path
|
tangential speed
