Unit Circular Motion and Total Energy

Question

How would one find the total energy of a ball being swung in a vertical circle? In this case the floor is being used as the zero point for gravitational potential energy.

In this example, the ball weighs 0.10 kilograms and is attached to 0.80 meters of thread. The lowest point of the circle is 0.20 meters above the floor. The speed of the ball is constant, and is 6.0 meters per second at the top of the circle.

Answer 1

Total Energy = Gravitation Potential Energy + Kinetic Energy

Gravitation Energy would be a function of height measured from the ground to the position of the ball

Kinetic energy would be 1/2 * m * v^2, where the velocity is the angular speed of the ball times the radius from the center of curvature of motion.

Anything else in specific?
