The 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 and released so that the pendulum swings back and forth with simple harmonic motion. Which of the following statements is true of this pendulum?

• The acceleration of m is a minimum when displacement is a minimum.

• The period of the pendulum varies as a function of m.

• The Kinetic energy of the pendulum is a maximum when its displacement is a maximum.

• The frequency of the pendulum varies with angle.
