Rotational Motion - Coggle Diagram

- - - - Linear Velocity (direction is tangent to the circular path)
  - - - Linear Acceleration (direction is tangent to the circular path)
        
        Total Linear Acceleration
        
        where...
- - - - A object that both translational and rotational motion also has both translational and rotational kinetic energy:
        
        When using conservation of energy, both rotational and translational kinetic energy must be taken account.
        
        All these objects have the same potential energy at the top , but the tim eit taken to get down the incline depends on how much rotational inertia they have.
- - - - The rotational inertia of an object of an object depends not only from its mass distribution but also the location of the axis of rotation.
- - - - If the axis of rotation fixed in direction: ω can change only in magnitude
      - If the rotation is counter-clockwise
        
        magnitude of ω is increasing, α points upward
        
        magnitude of ω is decreasing, α points downward
      - If the rotation is clockwise
        
        magnitude of ω is increasing, α points downward
        
        magnitude of ω is decreasing, α points upward
