    UCM 1 UCM 1 Presentation Transcript

    • Uniform Circular Motion
    • What is UCM?
      • It is when an object moves along a circular path at a constant speed.
    • Uniform= SAME Circular= ALONG A CIRCULAR PATH
    • Conditions Describing UCM Speed IS EQUAL to the Constant Velocity IS NOT EQUAL to the Constant This is because the direction is changing. = THE CONSTANT!
      • Acceleration does NOT equal zero
      • Fnet does NOT equal zero
    • During UCM the sum of all the forces acting on the object (Fnet does not equal zero) and the object is accelerating.
    • Incase of UCM the vectors for acceleration and force point towards the center .
    • Formulas Describing UCM
    • Centripetal Force Fc= Centripetal force m= mass ac= centripetal acceleration Centripetal force is any force (or combination of forces) that makes an object move in UCM
    • Speed Formula IS EQUAL TO Distance= Time= T
    • Radius of the circle (r) and time (t) it takes to complete a full circle are known. This time is called period of rotation (T). V= speed of UCM r= radius T= period of rotation
    • Centripetal Acceleration = centripetal acceleration v = speed r = radius
