A mass m is attached to the bottom of a string of negligible mass and Length L to form a simple pendulum. The mass is pulled back a small angle θ and released so that the pendulum swings back and forth with simple harmonic motion. Which of the following statements is true of this pendulum?
A. The acceleration of m is a minimum when displacement θ is minimum?
B. The period of the pendulum varies as a function of m
C. The kinetic energy of the pendulum is a maximum when its displacement is a maximum.
D. The frequency of the pendulum varies with angle θ
E. The length of the string L has no effect on the period of the pendulum.
