... Remember a reference height is needed for height. The direction of x is not important unless solving for x. If it is known that the answer is compression then –x is correct. If the answer is elongation then +x is correct. If one form of energy is not present then it need not be included in the equat ...

Work, Energy and Momentum
... On the other hand, the frictional force is path-dependent. In this case the longer the path between two given points, the greater the work. When the friction acts alone, the total mechanical energy is not conserved. The friction is therefore called a non-conservative or dissipative force. The mechan ...
