What is a Dependent Quantity?

A dependent quantity is a variable that changes in response to the value of another variable, known as the independent quantity. In simpler terms, the value of a dependent quantity is reliant on the value set by the independent quantity.

For example, consider the equation for the area of a rectangle, which is calculated as:

Area = Length × Width

In this case, the area is a dependent quantity, as it depends on the values of length and width. If you increase the length while keeping the width constant, the area will increase, demonstrating the dependent relationship.

This concept is common in mathematics, physics, and various fields of science where relationships between variables are studied. Understanding dependent and independent quantities is crucial for analyzing data and making predictions based on changes in variables.
