... The essence of our result that the line integral or path integral along a path between two points is independent of the path chosen is the Stokes’ Theorem which relates the surface integral over the curl to the “round trip” path integral around a complete path. Since it is always possible to define ...

... negative work on the hanging mass. As a result, the total work done by nonconservative forces will be zero. The mechanical energy of the system should be conserved as the objects move. If the system is released from rest, the initial kinetic energy will be zero. As the system begins to move, the mas ...

... According to Newton’s third law, the force Q exerts on P is equal in magnitude to the force P exerts on Q. Therefore A and B is wrong, because they both violate Newton’s third law. The only reason why the electrostatic repulsion between the two spheres (as calculated by Coulomb’s law) cannot lift Q ...

... It follows that Ui = Uf. Hence, U  0 . So from the first law, we have that Q   W . Thus, adding heat to the system will result in the system’s doing work on its surroundings. As such the cycle is a heat engine. Similarly, doing work on the system will result in the system’s losing heat. These ...

This momentum is proportional to duration of the interaction (this follows from the second Newton’s law), and the latte ...

... The force exerted by the catcher is opposite in direction to the displacement of the ball, so the work is negative. Or using the definition of work (W = F d cos q ), since q = 180o, then W < 0.
