The mass of the ball is inversely proportional to acceleration of a ball.
<h3>What is friction?</h3>
This question is incomplete but I will try to help you the much I can. Friction is the force that opposes motion. Friction depends on the nature of the surfaces in contact.
When the mass of the ball is large, the acceleration of the ball decreases since mass is inversely proportional to acceleration of a body.

In the real universe, no black holes contain singularities. In general, singularities are the non-physical mathematical result of a flawed physical theory.
B. The gravity acceleration is in the same direction as the force of gravity, and thus towards the centre of the earth
