Question

Based on the model equations, which would you expect to yield more preciseresults: a short pendulum or a long pendulum? Explain.

Answer 1

Changing the length of a pendulum while keeping other factors constant changes the length of the period of the pendulum.

Longer pendulums swing with a lower frequency than shorter pendulums, and thus have a longer period.

In this sense a longer pendulum would have more precision to measure times better.
