Scissors work by lever action. As you squeeze your fingers together, it causes the blades to cross one another which is how the cutting gets done. Then when you move your fingers apart, it opens the blades so that you can move to the next section of paper.

In physics and engineering, mechanical advantage(MA) is the factor by which a mechanism multiplies the force or torque applied to it.

The weight of a pair of scissors depends on many variables. However, a pair of seamstress shears weigh approximately four ounces. A pair of child's scissors weight about one ounce.
The amount by which a machine multiplies an input force is called?
mechanical advantage
What does the output force divided by the input force equal?
Efficiency of a machine or mechanical advantage
What is a explanation about lever and wedge to make scissors?
Scissors work as both levers and wedges. The lever part of the scissors is the handle being the input force (Fin), and the blade being the output force (Fout). The middle of the scissors that only turns and moves the smallest distance is the fulcrum. The fulcrum is what make the scissors a lever by having a "jack" for the scissors to sit on while the blade does all the cutting. The way to see if the lever is efficient or inefficient, you calculate the mechanical advantage of the lever. Mechanical advantage is calculating output force (Fout) by the input force (Fin) in Newtons. In the end. since you are dividing two numbers using the same unit (Newtons) the units cancel each other out. Therefore, leaving you with a number with no units of measurement to go with the final quotient. E.G MA= Fout/Fin = 3N/1N = 3 Scissors can also be used as a wedge. You see, (a) wedge(s) is/are (an) object(s) that split(s) (an)other object(s) apart. Scissors work as a wedge because the blades push whatever you are cutting apart from each other. Finally, making a pair of scissors a wedge and a lever.
What does IMA stands for in physics?
