|
Revolution |
Circular movement around a central object |
|
|
Rotational Motion |
Rotation around a fixed axis (angle of rotation) |
|

Uniform Circular Motion |
Circular motion at a constant speed |
|

Period |
The time it takes for an object to make one revolution |

Tangential Velocity |
The linear speed of an object as it moves in a circular path; Units m/s |

|
Angular Velocity |
Rate of change of angular displacement |

Torque |
A twisting force that tends to cause rotation |
|
|
Centrifugal Force |
Apparent outward force acting on an object moving in a circular path (does not exist) |
|
|
Centripetal Force |
force that makes a body follow a curved path. Its direction is always orthogonal to the motion of the body and towards the fixed point of the instantaneous center of curvature of the path. "center seeking force"
