The force of gravity is always down and constant, so the tension needs to change in order to keep the center pulling force the same. There are two forces on the ball, gravity and tension. For example, at the top of its path, the centripetal force must be down because that's the direction of the center of its circle of motion, but at the bottom, the centripetal force must be up. This is true because the ball needs the same center pulling force (centripetal force) throughout its path, but this centripetal force is constantly changing direction. The only the changing is the tension in the string. The ball's angular momentum is always constant since its mass, the radius of the circle it's traveling in, and its speed are constant. The string's pull on the ball is always perpendicular to the ball's motion, so it isn't doing any work, and thus has a constant rate of work. ![]() The force of gravity on the ball is always its mass times gravity, which is constant. ![]() Let's go through each answer choice one by one. ![]()
