Yeah; you turn a bigger wheel to drive a small one, so when you turn the big wheel you use your force over a longer distance, which causes the small wheel to have more power over a smaller distance
You need a velocity multiplier. A common example is a bicycle wheel.
The bottle opener is a lever.
Lever
Not necessarily. One type is simply a leveraged blade.
your face! ha ha ha really metal
Speed
Pulley are force multipliers because they expense the distance over which it operates.
Why are pulley force multipliers? Pulley are force multipliers because they expand the distance over which it operates.
Force and Speed <--- Science
if the distance is 5
Force Multiplier
Because it always has a mechanical advantage greater then 1.
That's their whole purpose. You push with a small force on one side, and get a much larger force on the other side. The end-effect is similar to that of a lever.
A "regular" can opener is a machine that combines a wedge (to cut through the top of the can) with a wheel and axle (which moves the can opener's cuttng wheel -- the wedge -- around the top of the can). The input force is provided by the operator, either by hand or via electric power. The output force is the separation of the metal of the top and the movement of the opener around the can. We also find that the can and the openers parts get a bit warmer with its use, and there are losses in the system due to friction.

With enough force behind it, nearly anything can kill you. If you somehow manage to cut an artery using the can opener, or if you cut yourself with it and got tetanus from it, you could die. Also, someone could kill you with a can opener if they hit you hard enough. On its own, a can opener cannot kill you, as it is an inanimate object.
finish the game then on your next play through you will get multipliers
