I think there is an error in d last questin Sal solved. the formula is

F= -K x D if you assume d right side as positive and d left as negative, the distance of 1meter is positive and the restored power which is counter to the force we apply should be negative.

-2N = -K x 1m

Which gives us 2 for the value of K.

If you apply -2 as Sal said to the formula

F=- K x D, It becomes F= 2 x D where restored F and applied F end up having same direction

Why do ALL educational videos teach people more in 10 minutes than their teachers do in 10 days?

@Stickbabiga Is the same as if you go and ask your teacher personally, he will explain the whole class in less than 5 min

@Stickbabiga I've noticed that teachers can teach people in 10 minutes as well, you normally see this when someone hasn't been in for whatever reason, I don't quite understand but I believe they take a lot longer so everyone has a good grasp of it.

When u pulled the spring 2N to the right the Resistance force is -2N. and since you move 1 meter,

F= - K X

-2N= -k * 1m

k= 2 not -2

Why worry about tenure? Just make Youtube videos.

Can you please make a video on Forces and Collisions?

Thanks! :))

thanks for the subtitles, i learn better by reading than listening. but both is just heaven lol

I disagree. I wouldn't call it unprofessional, I would call it conversation.  I actually like it, he sounds much more friendly than do many others in their tutorials, which helps me focus. I suppose it's just a matter of preference.

Its a shame he goes into much more detail on other topics but he cover just the tip here.

so when going to the left its negative and to the right its positive. am i correct
