1it will move towards the center n gain velocity in the mean time...
wen it will reach the center, it will overshoot n head forward coz of inertia of motion but,
it will get attracted towards the center, so, after a time, its forward velocity will become zero n it will start going towards the center agn...
n agn the same thing will repeat....
