When the rock tied at the end of the string and rotated the rock has two accelerations acting on it. One is tangential acceleration and another one is radial acceleration.
The rock has that tendency to move tangential but due to centripetal force, it is rotating in a circular path.
But when the string breaks the rock will move in a straight path.
This is because of the inertia because rock tendency is to be in a straight path but due to external force it was moving in a circular path but when the string breaks it moves in a straight line.
-- drop it on the floor; -- hit it with a hammer; -- heat it red hot in a flame; -- wrap many turns of wire around it and pass a high AC current through the wire.
A balanced equation shows that the number of moles of reactants is the same as the number of moles of products. This depicts the Law of conservation of mass where mass is never lost or gained.
