Problem with Deriving work done by gravitational force and gravitational potential energy fr...

Suppose we have a system with Two point masses of mass $M$ and mass $m$. And we want to derive Work done. Lets say M is fixed or $M>>m$. Initially assume mass m is at rest at a distance of $a$ from $M …

Why is time period same even if you give an impulse perpendicular to the spring?

It all started with this question. There are three different ways to solve this but one way is using kepler's second law. $\frac{dA}{dt}=\frac{L}{2m}.$ This applies because angular momentum is conser …
