A particle is moving along the x-axis subject to the potential energy function

Click For Summary
SUMMARY

The discussion centers on calculating the x-component of the net force acting on a particle at the coordinate x = 3.67 m, given the potential energy function U(x) = 1/x + x² + x - 1. The relevant equation for this calculation is delta U = -∫F(x)dx, which relates potential energy to force. Participants express difficulty in deriving the force from the potential energy function, indicating a need for clarity on the integration process and its application to find force.

PREREQUISITES
  • Understanding of potential energy functions in classical mechanics
  • Knowledge of calculus, specifically integration techniques
  • Familiarity with the relationship between force and potential energy
  • Ability to apply Newton's laws of motion
NEXT STEPS

Homework Statement



A particle is moving along the x-axis subject to the potential energy function U(x) = 1/ x + x2 + x – 1. Determine the x-component of the net force on the particle at the coordinate x = 3.67 m.

Homework Equations


delta U=-∫F(x)*dx

The Attempt at a Solution


I tried to take the integral of the given function from 0 to 3.67 but that didn't work and I tried plugging in the the distance into the equation and that didn't work either.

You need the force. How do you get force from potential?
