What is the ratio between maximum acceleration of pendulum oscillation and the gravity acceleration ?
Express the answer in terms of L (the length of pendulum string)
The Attempt at a Solution
amax = ω2 A = (g/l) L sin θ = g sin θ
So, the ratio is sin θ..
But, how to express sin θ in terms of L?
I know that for small angles, sin θ can be approximated to θ, and θ is arc length/L... Still, it's confusing
