Hi Mr Rees. Are you aware whether we need to know the bi-variate graphs for SHM? Like the elliptical/circular graph for velocity against displacement? I’m studying for AQA

@busyinverse4300 2 жыл бұрын

As the pendulum is released from max amplitude at second 0, it matches cos graph and therefore cos is used

at 11:59 , when you create a formula for the tension, isnt the tension the centripetal force in this situation, so shouldnt the equation be T = mv^2/r => mg = mv^2/r ?

@lexanris Жыл бұрын

Centripetal force is actually known as the net force of all the forces acting that causes the object to move in circular motion. So Fc=Tension-mg And tension=Fc+mg

I know I may not get a reply but. Why did you start the displacement from equilibrium then up to the max displacement rather than Start from Max displacement since the object is moving from rest

@ScienceShorts Жыл бұрын

Because we can start timing at any point after we've let it go. But yes, I wish I had done a cos wave instead.

@namename3130 2 жыл бұрын

A sin wave in maths does technically start at 0 but cos is just sin + 90 so people call that family of oscilation graphs, sin waves, as they are always a translation of a sin graph.

IF the mass is at equilibrium.[at rest]....wouldn't it velocity be equal to zero...thus the Kinetic energy will be zero at equilibrium..... As such k.E is an integer when the mass is moving in motion either going to the left or right...?
