Question

An illustration of a pendulum at 3 positions of a pendulum. the equilibrium position is labeled b. the other two positions are the maximum displacement of the pendulum labeled a and c. in between a and b are 3 lighter colored pendulum sketches equally spaced. in between b and c are 3 lighter colored pendulum sketches equally spaced. at which point(s) does the pendulum have the greatest potential energy? a only b only c only both a and c

Answer 1

Potential Energy + Kinetic Energy = Constant

The pendulum will have the greatest "potential energy" at points

a and c because the kinetic energy at those points is zero (zero velocity)

Potential energy depends on the height of the pendulum (proportional to)
