What is an example of a nonconservative force?
Air resistance.
What do nonconservative forces do to energy?
They dissipate energy.
What is the equation that includes initial and final energy and work done by nonconservative forces?
U0 + K0 + WNC = Uf + Kf.
Which term can be canceled when analyzing energy due to nonconservative forces?
WNC.
What expression should you plug in for K0?
mv^2 / 2.
What expression should you plug in for WNC?
FfD.
If Ff = μmg, how do you solve for μ?
