If Kofi is standing on a hillside that slopes down towards the east, and he drops a ball, in which direction will the ball roll?

Make your response very short.
The ball will roll towards the east, following the slope of the hill. Gravity pulls objects towards the center of the earth, and since the hill is sloping downward in that direction, gravity will cause the ball to roll downhill. The steeper the slope, the faster the ball will accelerate in that direction.
