... A roller coaster of mass m starts at rest at height y1 and falls down the path with friction, then back up until it hits height y2 (y1 > y2). An odometer tells us that the total scalar distance traveled is d. Assuming we don’t know anything about the friction or the path, how much work is done by fr ...

Chapter 7 Potential Energy and Energy Conservation
... We were able to define potential energy associated with work done by gravitational and elastic forces. All such forces are called conservative forces. Work done by conservative forces: • can always be expressed as difference between initial and final values of a suitably defined potential energy • it ...

... 37. (a) We first multiply the vertical axis by the mass, so that it becomes a graph of the applied force. Now, adding the triangular and rectangular “areas” in the graph (for 0 x 4) gives 42 J for the work done. (b) Counting the “areas” under the axis as negative contributions, we find (for 0 ...
