This question isn't for a specific problem. Just knowledge to approach a series of problems.
It concerns a problem where a uniform sphere rolls smoothly down a ramp at incline theta. There is a static frictional force on the ramp. I can go on to find acceleration I am just unsure as to the role of the force of friction in the energy equations.
The Attempt at a Solution
I'm just Unsure as to whether The force of static friction should be included in the original energy equation or not:
mgh = 1/2mv^2 + 1/2Iw^2 + Fx ???
