Variable ‘G’ Pendulum

SKU Item Code: SK064 Category

Principle and Working:

Additional information

Salient Features

  • Hand-held digital timer with membrane keypad.
  • Investigate the pendulum oscillation in the vertical plane, the horizontal plane, and for any angle in between.
  • Simulate the pendulum oscillation as it would behave on the moon.
  • Automatically measure the oscillation period using the light barrier.

Objectives

  • To measure the period of oscillation of pendulum, by changing the angle θ.
  • Effect of large amplitude on time period.
  • To measure the period of oscillation by changing the length of pendulum.
  • As the variable g-pendulum also allow to vary the acceleration due to gravity acting on pendulum.
