The period T of a simple pendulum can be calculated using where l is the pendulum length and g is the gravitational field strength. Using a single value of length and period, we can determine the acceleration due to gravity. However, it would be better experimental practise to vary the length of the pendulum and ... <a title="using linest to obtain a gradient and uncertainty" class="read-more" href="https://mrmackenzie.co.uk/2018/06/using-linest-to-obtain-a-gradient-and-uncertainty/" aria-label="Read more about using linest to obtain a gradient and uncertainty">Read more</a>
