Total energy of a body in a circular orbit

Click For Summary

Homework Help Overview

The discussion revolves around determining the total energy of a particle in a circular orbit, focusing on the interplay between potential and kinetic energy under the influence of a central force.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants explore the nature of the forces acting on the particle, questioning how to derive the kinetic energy given that the work done by the central force is zero and energy is conserved.

Discussion Status

Some participants have provided insights regarding the centripetal force and its role in maintaining the circular motion, while others are still seeking clarity on calculating kinetic energy.

Contextual Notes

There appears to be an assumption that the particle is influenced solely by a central force, and the discussion is constrained by the need to adhere to homework guidelines regarding the level of detail in solutions.

Homework Equations



The Attempt at a Solution



Is the particle moving under the influence of a single central force ?

Since the force always acts towards the center , work done by the force is zero . Energy is conserved . Potential energy at a particular radius can be found . But how do we find the kinetic energy of the particle ?
