Simple harmonic motion

Please stop being such wannabe wise asses and admit that this video is perfectly right!

[zaroonx]

when velocity is zero how can acceleration be maximum????

[PelletierPhysics]

@zaroonx Because velocity is changing?

[PIGORILLA]

@zaroonx because u dont need to have velocity to have accelaration...For example when u start ur car velocity is zero but the moment u hit the throtle u accelerate...

[PumpManufacturers]

nice education stuff

[kcronoss]

it's wrong :}

because when the movement begins, the speed is 0, not maximum

but during the movement when the object passes through the point O, the speed is maximum.;}

[PelletierPhysics]

@kcronoss

The video begins while the velocity is maximum, at the middle position (x=0).

[CDRphoenix]

@kcronoss You are incorrect; the video is accurate. Watch it more closely.

huh?? i failed :'(

[MrChloroflorocarbon]

nice and quick educational video thanks.

[miaz94]

what is X??

[stereocomets]

@miaz94 displacement!

[gatoradeee]

@miaz94 is is the position (vertical)

[thephishman10]

The version of this is better

[bd6m20]

you're velocity function seems off. shouldn't there be 0 velocity at A and -A? Also, shouldn't velocity have it's steepest slope midway between A and -A, at V max?

[PelletierPhysics]

@bd6m20 There is zero velocity when position is A and -A, has seen on the graph. However, velocity has zero slope (acceleration) when it reaches its maximum value. The velocity function is simply the derivative of the position, I don't see what could be wrong with it.

eso es una funcion senoidal con respecto al resorte

[datzfast]

question is the sinusoidal shape also a parabola ? i was thinking of an automated method of grinding mirrors

[fabriciosb2]

@datzfast no, its not!!

[pablo0otje]

that sh*t is top secret you cant post that on the internet

[tchab05]

can u explain lol

[rampriyadarshini]

WOW.....awesome

[ohgoodlord]

i was lost but now im found! thx

[domyaska]

excellent !! grazieeee milleeee

[seigakufuji]

thx :)

[seigakufuji]

thx :)

[technohunger]

now i see how it works..thanks

Elucidating. Thanks! :^)
