Question

A seesaw weighing 3 lb/ft of length is being used. What factor primarily influences the seesaw's balance?

a) Weight of the object
b) Length of the seesaw
c) Distance from the fulcrum
d) Force applied

Answer 1

The distance from the fulcrum primarily influences the balance of a seesaw.

Step-by-step explanation:

In a seesaw, the factor that primarily influences the balance is the distance from the fulcrum. The farther an object is from the fulcrum, the greater its lever arm and the greater its turning effect. This means that even if the weight of the object on the seesaw changes, as long as the distance from the fulcrum remains the same, the balance will not be affected. The weight of the object, length of the seesaw, and force applied are secondary factors that can affect the balance, but the distance from the fulcrum is the primary factor.
