If you where to go in an elevator step on a scale and go down
You are currently reading a thread in /sci/ - Science & Math
If you where to go in an elevator step on a scale and go down you would "weight less" Because of the normal force being reduced.
Is this because since force is mass times acceleration and when you go down you accelerate downward therefor cancelling out the normal force? Also what if you stopped accelerating and went at a negative velocity (Downward) would the normal force already be cancelled out from before and not come back?Also what if you where to move faster than gravity (-9.81) would you experience a "negative normal force" or like complete cancellation of normal force and a new force pushing you upward?
Am I at least close?

wtf
you would just free fall

draw a goddamn FBD like they do in high school

you do chincy little FBD's all the time in college. its often a part of showing your work.

What fucking major do you have that you still do HS physics in college?

>If you where to go in an elevator step on a scale and go down you would "weight less"
this will only be the case while the elevator is accelerating down. once the elevator stops accelerating (reach a constant speed) the number on the scale will be correct
>Also what if you where to move faster than gravity (-9.81)
you seem to be confusing acceleration and speed together.

not really, I recommend watching some physics videos on khanacademy

are you even in college? doing FBD's is a staple for all of classical mechanics.

No? I mean I believe you that you had to do it, but isn't that kinda redundant at that stage?
