A ball is held at a height H above a floor. It is then released and falls to the floor. If air resistance can be ignored, which of the five graphs below correctly gives the mechanical energy E of the Earth-ball system as a function of the altitude y of the ball?
Which of the five graphs correctly shows the potential energy of a spring as a function of its elongation x?
As a particle moves along the x axis it is acted by a conservative force. The potential energy is shown below as a function of the coordinate x of the particle. Rank the labeled regions according to the magnitude of the force, least to greatest.
The diagram shows a plot of the potential energy as a function of x for a particle moving along the x axis. The points of stable equilibrium are:
