A small steel ball bearing is released from rest at the surface of a deep column of engine oil. It falls vertically through the oil until it reaches terminal velocity.
How do the acceleration and velocity of the ball bearing change as it falls through the oil?
The acceleration remains constant, and the velocity increases at a constant rate.
The acceleration decreases to zero, and the velocity increases to a constant value.
The acceleration increases, and the velocity decreases to a constant value.
Both the acceleration and velocity decrease to zero.
