Imagine trying to move a bowling ball that is sitting on the carpet. Let's say you are throwing little plastic ping pong balls at a certain speed at the bowling ball. A single ping pong ball will not move the bowling ball. Therefore will throwing another ping pong ball each second ever move the bowling ball? What do the ping pong balls and bowling ball represent with regard to the photoelectric effect?

So this is an analogy where I want to compare the ping pong ball the bowling ball the carpet

to the photons electrons being ejected metal service.
