Answer to Question #161660 in Physics for Ines Ransom

Question

The directions of the two forces acting on the ball bearing as it falls through the oil drag and weight.

explain in terms of the forces shown why the ball bearing reaches its terminal velocity

Answer 1

According to Newton's first law, the body moves at constant rate when it is subjected to the action of forces in equilibrium. Thus, we conclude that the ball bearing moves at constant terminal velocity because the force of gravity and drag force are equal in magnitude but opposite in direction.
