* when a force is applied on a sphere resting on a plane, initially it slides, and then it starts rolling - how long it slides and how long it rolls!
* if the force is not directly through the centre of the sphere then a component of the force tends to create a spin on the sphere. the sphere tends to traverse in a curvilinear path. what would be the equation of the path and how it is affected by the spin!
* what would be the combined effect of rolling and spining of the sphere! how to express it!
* when force is applied some where below(/above) the centre of the sphere, it may jump up from the plane - but under what cirstances it happens! how to describe its path! OR under what cirstances the z-axis movement of the sphere is affected and by what amount!
