C1 practical: Measuring g with a pendulum
You will probably know that the time period of a pendulum is related to its length, the longer the pendulum the longer is the time period, however you might not know that the period is also related to the gravity. If you took a pendulum to the moon it would swing more slowly so have a longer time period. In this experiment you will measure the acceleration due to gravity (on the Earth) by measuring the time period of...
