    Undergrad How Does the Work-Kinetic Energy Theorem Apply When Raising a Ball Vertically?

    Assume a situation that there is a ball on the ground. A vertical force is applied to raise the ball to h at a constant speed. According to work-kinetic energy theorem, no net work is done on the ball owing to the constant speed. However, the potential energy increases as the ball gains...
