I was so confused, I was like he must mean a foot... I began to brainstorm about the possibilities of forcing the matter into a negative version of itself, Not fruitful at all just stupid hahahaha
You should've just re-made this, it is soooo confusing 😂 The concept makes sense but the inch/foot thing just keeps throwing me off, especially since you keep going with the error for the duration of the video.
Excuse me: if infinitesimal movement is dx in right direction, force is - k x because force is opposing to the movement and therefore force points on the left. So W = - 20/2 * x^2. In fact work is negative because it's resistent, isn't it?
He made it up in order for the problem to be solvable. In order to find k, the problem either has to directly give you k, or give you F and x. For this example he used F = 10 and x = -1/2 to solve for k
The Spring is one foot! - not one inch. Sorry about that folks!

Pushing it through the wall
That pen twirl @ 0:42 was slick
I try ;)
I think he meant 1 foot not 1 inch? Because he said 6 inches was half
I absolutely did. Thanks for the catch!. I'll see if I can make a note of this.

thank you
Isn't it -kx?

You're welcome!
You are tooo good
Why do we have to subtract the limits of integration by the range of stretching or compression when we're given the length of the spring?
where did you get the 10 from at 1:42 ?
Because it take 10lb of force to compress the spring 6in.

Wait does that diagram mean you compressed the 1 inch spring by 6 inches???
He means 1 ft not 1 inch. Bit of a stonehenge moment
Very sorry, I meant one foot. Thanks for the catch!
