PLANAR KINETICS OF A RIGID BODY: WORK AND ENERGY
... independent of the path. In this case, the work depends only on the initial and final positions of the object with the path between positions of no consequence. Typical conservative forces encountered in dynamics are gravitational forces (i.e., weight) and elastic forces (i.e., springs). What is a c ...

... 50. IP An 81.0-kg in-line skater does 3420 J of nonconservative work by pushing against the ground with his skates. In addition, friction does 715 J of nonconservative work on the skater. The skater’s initial and final speeds are 2.50 m/s and 1.22 m/s, respectively. (a) Has the skater gone uphill, ...
