The Simple Pendulums – Errors
The following is a diagram of the kit used:
The following describes the method we used to collect the data:
- Attach a piece of string to the tripod.
- Attach the metal weight to the end of the string.
- Now that the string is taught, measure it using a ruler.
- Adjust the string length until it is 150mm long from the very top of the string to the very top of the metal weight.
- Holding a ruler horizontal to the ground and at the same height as the metal weight, pull the weight 62mm using the ruler as a guide. Remember to keep the string taught.
- On the instruction of the timer release the weight.
- The timer should have his eyes at the same height as the metal weight.
- Record the time on the moment the weight finishes it’s second cycle.
- Repeat 5 times and then do the same for 220, 290 and 480mm.
- Now follow the above method but for an amplitude of 190mm instead of 62mm.
