As already covered, the gravitational field strength at a point in space is given by the force experienced by a unit mass placed at that point, and gravitational field strength due to a point mass can be easily calculated by the ratio of the force experienced by a test mass placed at that point. In […]

There are several situations of collisions in rigid body dynamics on which different problems are framed. In such cases we need to conserve angular momentum of the system about a point with respect to which the net external torque on the body is zero. The most important thing in such cases is to locate a […]
