One last thing:
Last time I checked, a derivative was just a scalar, so it can only be positive or negative. How can you derive any direction for the force from this?
An example: dU/dX = 10J/m at a displacement -.5 m for a rock being loaded onto an elastic slingshot. Origin is at relaxed...
Ahhhhh! I think I see it now! "I can see clearly now, the rain is gone!" lol.
My problem what that I was thinking about it with respect to time instead of distance.
Here's my current understanding:
Let's say I have two positive point charges, one held in place. Let's say I'm far away from the...
Hello Everyone,
I am having a very difficult time intuitively understanding the formula -dU/dx = Force(x). I don't want help deriving it, I'm simply looking for an intuitive understanding about why this might be true. An example with gravity would really help.
My thoughts so far: I find...
