Question 1 of 32
A pendulum is lifted to a certain height and then released, which causes the
pendulum to swing back and forth. If energy losses due to friction and air
resistance can be ignored, when is the kinetic energy of the system at its
maximum value?
OA. The kinetic energy of the system peaks when the pendulum is at
its maximum height.
OB. The kinetic energy of the system peaks when the pendulum is at
the bottom of the arc.
OC. The kinetic energy of the system peaks when all forces are in
equilibrium.
OD. The kinetic energy of the system is constant throughout the
periodic motion.
