Pendulum (Jumping Pendulum)

• Drag the pendulum bob to one side and release.
• The bob will (i) oscillate, or (ii) undergo a complete or incomplete circular motion, depending on the level of release and whether or not the pendulum is interrupted by the pin.
• Assumptions:
  (1) All frictional forces are negligible.
  (2) The string is inextensible.
  (3) The radial velocity of the bob will disappear instantly when the string becomes straight after a free fall.
