My mind was blown because I didn't know the equation E = 1/2 *k* x^2 could be also obtained simply by substituting F. It makes a lot of sense.

Why is the area under the graph equal to the energy stored??

This only applies for the period where the material is obeying Hooke's Law, right? If so, does that mean that using the area under the graph to calculate energy is only applicable before the limit of proportionality?

you need a pair of forces to stretch a spring. one is the gravitational force, what about the other one? is it the reaction force or a frictional force? where on the spring does the other force act?

I'm watching this out of interest not for a-level. I'm slightly confused by the notation of _F_ and _x_. I will also refer to _x_ as _d_ from now on because it is distance. We know that _E = Fd_. The area under a graph is the _x axis * the y axis_. For example on a speed-time graph where the _y_ is speed and the _x_ is time, the area under the graph is distance which is _speed * time_. It seems to me that the area under the graph in your video is also _the x * the y_ because the area underneath is _E = Fd_. However you said that _E = Fd/2_ because by _F_ you mean the FINAL force applied over the distance rather than the AVERAGE force applied over the distance. You have now ended up with the equation _E = Fd/2_ even though _E = Fd_ because your definition of _F_ was different. How does this work in physics with the different possible meanings of F and contradictory equations? Is there a way to notate this difference (between final and average force)? By the way I have never learnt calculus and I know this has something to do with integrals so that may be where my confusion is. To me my way seems more correct because it is done the same way as in a distance time graph, it works for any shape of a graph, and you end up with the correct _E = Fd_ equation. Thanks for any help!

Hello; can you please explain why the work done by the spring is not W=Fs? I don't understand why this doesn't apply here.
@PhysicsOnline

MrMas9 because the force increases as the spring extends.

Can anyone tell me how to prepare for the simple harmonic motion ISA paper? I'm going to do the paper in 16 days and although I've answered all of the SHM questions in the AQA book, I still feel unprepared.
