Homework Statement
If I have a ball moving in a circular path (ball is connected to a string), as shown in this picture:
http://w3.shorecrest.org/~Lisa_Peck.../circularmotion/Images/cent_force_on_ball.gif
should I say that the energy of the ball is both its kinetic energy (1/2)mv^2 and its rotational kinetic energy = (1/2)Iomega^2?
Homework Equations
kinetic energy (1/2)mv^2
rotational kinetic energy = (1/2)Iomega^2
The Attempt at a Solution
I was just thinking about this. I mean, what if you have a car moving in a circle--do you consider both kinetic energy and rotational kinetic energy?
