Homework Statement how does F = -KX become A = -KX where A = -W^2 X A = acceleration x = displacement k = constant f = force Homework Equations The Attempt at a Solution

I'm doing an experiment with a real pendulum and I am able to calculate the period quite accurately using a motion sensor which draws a graph for me on a computer and provides information. how do i prove that a real pendulum doesn't move in a SHM. for e.g Length of pendulum : 0.5m...

Is it possible to prove that a real pendulum does not move with SHM? and does SHM create a sin graph?

is 'SHM' what a pendulum creates?

how does the pivot cause friction? Thanks Hootenanny.

OK, what causes a real pendulum to stop?

But real pendulums are subject to friction and air drag, so the amplitude of their swings declines.

is that even possible ignoring air resistance?

doesn't it stop due to air resistance etc.

Homework Statement I need all the variables that causes the pendulum to stop. Homework Equations The Attempt at a Solution I know friction causes the pendulum to stop but what type of friction is it and what from? thanks
