Next: Mobile perpendicular (cd), Previous: Mobile circular (cd), Up: Circular dynamics [Contents][Index]
Mobile with circular motion described by polar coordinates. A positive value to tangential velocity, mean that the mobile tour in the opposite sense of clockwise. And a positive value to radial velocity, indicates that the mobile moves away from the center of rotation. Allows only one force (not friction), that represent a radial force.
|Equations:||1 if there is present a force, in other case 0.|
|vt:||Tangential velocity of the mobile.|
|y:||Y coordinate of the mobile.|
|vr:||Radial velocity of the mobile. If this data is unknown, the result will be the positive value.|
|ar:||Radial acceleration of the mobile. If this data is unknown, the result will be the positive value.|
