Aim
To study how the time period of a simple pendulum depends on its length, and to find the acceleration due to gravity, g.
Time 20 oscillations of a pendulum at different lengths, swap a heavy bob for a light one, and find g from the L-T2 graph.
What you'll explore
- Time period Depends on length, not mass.
- Finding g g = 4 pi2 x slope of L against T2.
Who it's for
Class 11 physics, for CBSE, ICSE and State boards. It follows the practical in your textbook: time period, length, mass, g.
