Force diagrams, Balanced Force and equilibrium? Same difference

So in my last post I explained balanced force as anything that had equal forces so that it wasn't moving. That can be called being in a state of equilibrium.

So take this for an example. You place an apple on the table and it stays perfectly still. First off, what forces are acting on the apple? The table is acting straight up, and the force of gravity is acting straight down. You can draw that out to be a force diagram. That is a diagram which is used to visually represent every force that is acting on an object.

But back to the apple, it is perfectly still. That means that to force put on the apple by the table and the force put on the apple by gravity are equal. That apple is in a state of equilibrium. This literally means that it is balanced.
