Homework Statement Given: The electric potential function: V= 3x^2 + 2xy +(y^2)z + 20 a) A 4 coulombs, 2kg charge is released from the origin. Determine the speed of the charge at (1,1,-1) Homework Equations Kinetic Energy= 1/2 mv^2 The Attempt at a Solution I tried to use the fact that the...

Thank you so much for your help! It makes sense now!

Not that I don't believe you, of course. It's just satisfying to be able to prove it to myself.

Oh, I see what you're saying! Out of curiosity, how would I go about proving mathematically that this slightly larger initial force and lower final force cancel each other out?

My question isn't a homework question, it's a general conceptual question. We were going over a "work" problem in class and our professor told us that the work required to lift an object up to a certain height was equal to "mgh". However, is this only the case when we assume that acceleration is...
