SUMMARY

The force components derived from the potential function U = 7x^2 + 9xy + 3(y^2)z are Fx = -14x - 9y, Fy = -9x - 6yz, and Fz = -3y^2. The calculations for Fy and Fz were confirmed as correct, while the accuracy of Fx was initially questioned but ultimately validated by peers in the discussion. This confirms the application of partial derivatives in determining force components from a scalar potential function.

PREREQUISITES
  • Understanding of scalar potential functions in physics
  • Knowledge of partial derivatives
  • Familiarity with vector calculus
  • Basic algebra skills for manipulating equations
NEXT STEPS

Homework Statement



If U = 7x^2 + 9xy + 3(y^2)z, what are the components of the force vector F ?


The Attempt at a Solution


These are the answers I've come up with. I've gotten Fy and Fz correct, but the Fx is wrong and I'm pretty sure its actually right. However, I would love to be proven wrong lol.
Fx=-14x-9y
Fy=-9x-6yz
Fz=-3y^2

Well, your Fx looks right to me. :smile:
 
yeah, I'm about to message my professor lol.
