Question

When you are using scissors, what are you improving?

A. Mechanical advantage
B. Potential energy
C. Buoyant force
D. Fricitional Force

Answer 1

Using scissors improves mechanical advantage.

Step-by-step explanation:

When you are using scissors, you are improving mechanical advantage. Mechanical advantage refers to the number of times the input force (the force you apply when using the scissors) is multiplied to produce the output force (the force the scissors exert on the object being cut). Scissors are designed to increase the mechanical advantage, making it easier to cut through materials.

This is governed by the relationship between force and torque, which allows the input force applied to the handles to be multiplied, making it easier to cut through materials. Simple machines like scissors do not enhance potential energy, buoyant force, or frictional force in their primary operation.
