7
Q
What is the equation for mechanical energy?
A
E = KE + PE
8
Q
What is the equation for the conservation of mechanical energy in the absence of non-conservative forces?
A
Ei = Ef or KEi + PEi = KEf + PEf

Q
What is the equation for the conservation of mechanical energy in the presence of non-conservative forces like friction?
A
Ei + W by nc forces = Ef
