Unformatted text preview: θ to be smaller or larger than it would be if there were no drag? Drag causes the angle θ to be smaller Does the drag cause the height h to be smaller or larger than what it would be if there were no drag? Since drag causes the angle θ to be smaller and = -h L Lcosθ (L remains constant regardless of drag), Does the drag cause the potential energy gained by the pendulum to be smaller or larger than it would be if there was no drag? Does the drag cause the velocity V of the pendulum to be smaller or larger than what it would be if there were no drag? Does the drag cause the calculated velocity v of the ball to be smaller or larger than what it would be if there were no drag? Θθ...
