The ratio of net force exerted on an object and its acceleration is mass.

This is a fundamental principle in physics known as Newton's Second Law of Motion:

* Force (F) = Mass (m) x Acceleration (a)

Therefore, if you rearrange this equation to solve for mass, you get:

* Mass (m) = Force (F) / Acceleration (a)

This means the ratio of net force to acceleration directly corresponds to the object's mass.
