Question

why the sparks coming out of a grinding stone are tangential to the rotating stone?

Open in App

Solution

The sparks coming out of a grinding stone are tangential to the rotating stone. It is due to directional inertia. Once the sparks are produced, no external force acts on the sparks and so the direction of motion cannot change. The sparks so produced follow paths tangential to the grinding stone.
