## Motion Under Central Forces (part 2)

This article covers topics like Law of conservation of energy, Equation of motion and Form of motion under the effect of central forces.

## Law of conservation of energy

From equation 4 we consider
$f(r) = – \frac{{du(r)}}{{dr}}$
then this shows that $f(r)$ is not only a central force but a conservative force. In this condition this equation

## Motion Under Central Forces (part 1)

This article covers an introduction to central forces , equation of motion under central forces and

## Introduction

If the force $\mathop f\limits^ \to$ acting on a body has following characteristics then it is a central force
(i) it depends on the distance between two particles
(ii) it is always directed towards or away from a fixed point.
Gravitational force is an example of central forces. Mathematically if we
consider central point as origin
