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
then this shows that is not only a central force but a conservative force. In this condition this equation
This article covers an introduction to central forces , equation of motion under central forces and
If the force 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
