Simple machines come to mind.
Let us say a pulley is suspended on a secure structure. One end of the rope is tied to a heavy object. The rope makes a few round on the pulley. The other end of the rope comes out and can be held with relative ease to keep the heavy object afloat or lift it up. The human effort would be 'n' times less than the weight of the object, where 'n' is the number of times the rope winds around the pulley.
A lever is another example. The beam is resting on a fulcrum. One downward force (F1) is acting L1 meters from the fulcrum. The balancing downward force (F2) will be L2 meters from the fulcrum on the other side. The principle of moments says that F1 * L1 = F2 * L2. With a rigid beam (the beam does not break with the forces). If L1 = 2 * L2, then F1 = 0.5 * F2.

Is a seesaw a force multiplier or a speed multiplier?
force multiplier
Is the arm lever a distance multiplier or a force multiplier?
Well, i'd say its both. depends on the case to specify when it is a force multiplier or a distance multiplier.
Is a screw driver a force multiplier?
Force multiplier. It an inclined plane so a smaller force is acting over a greater distance
Can you give an example of a machine that increases speed?
You need a velocity multiplier. A common example is a bicycle wheel.
Is can opener a force multiplier's Why?
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

Is gear a force multiplier or a speed multiplier?
Both. A small driving gear and a large driven gear is a force multiplier. Whilst a large driving gear and a small driven gear is a speed multiplier

Is a golf club a speed or a force multiplier?
AnswerA golf club is a speed multiplier
How is a bicycle a force multiplier?
yes
Are stairs force multipliers or speed multipliers?
Speed
What is the difference between a force multiplier and a speed multiplier?
A force multiplier increases the effort force and the mechanical advantage is larger than one (Which means it is easier to move a large load with a small effort). While the speed multiplier does not make the effort easier but makes the load move through a larger distance than the effort. The mechanical advantage of a speed multiplier is usually lower than 1.
How did the pulley affect the amount of force needed?
A pulley is a force multiplier. (it swaps force for distance).
