An ideal pendulum is often discussed when studying simple harmonic motion. What are the conditions needed for an ideal pendulum? Choose three correct answers.

A frictionless pivot lets the pendulum swing without energy being lost to friction. Gravity pulls the mass downward, and as the pendulum swings toward equilibrium, its inertia carries it through that position. The rod’s mass distribution is not a required condition for an ideal pendulum, and tension acts along the rod toward the pivot, not downward.
