What effect does the mass of the ball have on the period of a simple pendulum? What would be the
effect of replacing the steel ball with a wooden ball, a lead ball, and a ping pong ball of the same size?

Answer:
Mass of the Bob does not affect the time period of the pendulum.
Question:
What would be the effect on simple pendulum for replacing the steel ball with a wooden ball, a lead ball, and a ping pong ball of the same mass?
Answer:
If they are all the same mass, and the center of mass is in the same location, the pendulum would have close to the same period. I say close because air resistance would affect a ping pong ball but would have almost no effect on a much smaller lead ball of the same mass. A ping pong ball of the same mass as a lead ball would be relatively much, much larger than the lead ball, so it would be subject to air resistance.
Another factor with the ping pong ball would be rotation. As the ball swings back and forth, it also rotates back and forth. So there is an acceleration and deceleration as well as swinging back and forth. The lead ball, having a much smaller radius, would be easier to rotate. With the ping pong ball, all the mass is on the circumference of the ball. With the lead ball, it’s solid all the way through and of much smaller diameter, so the rotation back and forth would be more easily done
