(We’ll neglect the gravitational force of the sun.) Thus, if we calculate the change of momentum of the lander, we automatically have the change of momentum of the comet.

In this example, water contracts upon heating, so if we add heat at constant pressure, work is done on the water by surroundings and therefore, Cp is less than CV. the sum of parts (a) and (b); d.

Equivalently, a force is conservative if the work done over any closed path is zero. A non-conservative force is one for which the work done depends on the path. The component of a conservative force, in a particular direction, equals the negative of the derivative of the potential energy for that force, with respect to a displacement in that direction.
