Objective: Conservation of Energy I
... For instance, a frictional force would oppose the motion and “slow” the car down. Unlike gravity, friction would do negative work on the car through out the entire trip, on both the up and down parts of the motion. The truth is that MOST moving objects experience non-conservative forces, such as fri ...
