Chen and Naledi are standing on a hillside that is sloping downwards towards the east. If Chen lets go of a spherical ball, in which direction will Naledi see the ball roll? Provide a very short response.
Naledi will see the ball roll towards the east, downhill. This is because gravity pulls objects towards the center of the Earth, and on a slope, the direction of gravity's pull will cause the ball to roll downwards along the path of least resistance, which is towards the direction the hill is declining, in this case, towards the east.
