Yes, it has 0 potential energy at its lowest point, all the potential energy becomes kinetic energy.
A pendulum, 1.0m long is pulled aside to the position where the 4.00g "bob" has been raised vertically a distance of 10cm. Find:
a) The potential energy before it is released. I got an answer of about 0.00380 J
b) The kinetic energy at it's lowest position. This is the troubling question. I said it is 0.00380 J is that right?
