What happens if your drill a hole through the centre of the Earth and drop a ball into it? [|Travelling through the centre of the Earth]

[|Answer:] The ball will start accelerating at the rate of 9.8m/s2 and will continue to do so untill it reaches the centre of the earth. At the centre, the velocity of the ball will be infinitely large. Since the velocity is infinitely large at the centre, it will keep on moving towards the other side. Therefore as the ball will progress towards the other side of the hole and away from the core, its velocity will start to decrease and there will be negative acceleration at the rate of 9.8m/s2. The reason being it will be travelling in the opposite direction of the gravity. The velocity will be decreasing and will be 0m/s at the tip of the other side. If no one catches it, the ball will go back again towards the other side and the cycle will continue. It will keep on going back and forth inside the hole.
