Homework Statement


What could be the reason why the graph is formed the way it is?

Homework Equations



τ = 2π(L/g)^(1/2)

The Attempt at a Solution


I don't know how to explain it. Anyone know why one is a linear and another is a curve?

An equation of the form y=ax+b is the most general form a linear equation. If you square your original equation can you see how it must have a linear form if y=τ^2 and x=L?
