Exp-1 To investigate the oscillation behaviour of a pendulum (rod pendulum) by varying the magnitude of the components of the acceleration due to gravity.

Exp-2 Measure the period T for various pendulum lengths L.

- Hand-held digital timer with data logging facility & membrane keypad.
- Small slits on the inside edge of the photogate for emitting & receiving infra red beam.
- Many other experiments can also be performed with the same timer.
- Quick & accurate results.

- Oscillation period.
- Harmonic oscillation.
- Mathematical pendulum.
- Physical pendulum.
- Decomposition of force.
- Moment of inertia.

The pendulum used here can act as a mathematical (simple) pendulum. However, depending on the position of the pendulum weight, the length measured between the pivot point and the centre of the moveable weight can be varied.

In the present setup one can rotate the oscillation plane around the angle θ with respect to the vertical plane thus altering the value of ‘g’. The time period of oscillation at angle θ is given as:

**T(θ) = 2π(L/ g _{eff} )½**
