Force multiplication

Force multiplication is when you use something to multiply the amount of "force" or power you have. An easy way to understand it is to think of it like money. If you had $10 and you wanted to buy something that costs $20, then you could use your $10 along with a friend's $10 and together you'd have enough money to buy the item. That's kind of like force multiplication - you're using something else to increase your own power.
