![]() Which means that the acceleration was negative K over M times X. So in mass spring systems, as soon as you let it go, the restoring force, the restoring force was back towards the center and that restoring force was equal to negative K. And this is basically just equal to the maximum angle that you pull it out for. So now it happens it's gonna oscillate between these two points. And now we're gonna pull this mass out to some theta, some angle theta. ![]() So except we've got a pendulum of length L. And we say that those amplitudes were basically equal to the maximum displacements that we pulled them away. And so given some spring constant here and given the fact that we pulled it out to some amplitude, it would just go back and forth between those amplitudes. So let's take a look when we had a mass spring system, we would take this mass and pull it out and then let it go. It's just the letters are gonna be slightly different. So it means we're gonna see the same kind of equations. And what we're gonna see is that just like mass spring systems, pendulums also display simple harmonic motion. Hey guys, so for this video we're gonna take a look at a different kind of simple harmonic motion.
