ok people, tomorrows test is the last one, and its on physics, but being me there are a few things im not quite sure on, so as im revising ill be contuelly adding to this thread with things im not to sure on.

firstly.....pendulms

how do you work out the maximum acceleration of a pendulm, i know how to work out the max velocity, but im stumped witht the max accleration?

also if you know the frequency, and the amplitude, how can you get the weight of the pendulm from that

thanks
