I got my october exam grades last week and I got an A!!!! Thank you for your vids they helped me so much especially as I didn’t have a teacher. My final grades are now A*AA!
As someone who has just finished first year of sixth form I'm trying to understand first two topics for each subject by the time I go back to school to give me a leg up. Found the video very useful 😃
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.
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
A.O.A Good work, sir hamari physics ki books mein simple harmonic motion dot dall kr likha hota tha jaisy k S.H.M but aj kl k adition mein aisy likha hota hai (SHM) why? Explain me plz thanks,
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
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 ?
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
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...?
i Knew he was british through his accent but he confirmed it by writing centre instead of center (but who cares this is a great expalaination for simple harmonic motion)
the potential energy curve only applies to gravitational systems, right? e.g it wouldn't be the same for a mass on a spring moving horizontally across a surface?
