what is the relationship between Force, area and mass.​

Answers

Explanation:

It states that the rate of change of velocity of an object is directly proportional to the force applied and takes place in the direction of the force. It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²). Thus, an object of constant mass accelerates in proportion to the force applied.

Froce is equal to mass multiplied by area

froce= mass × area

In turn formula can be twisted so

Force/mass= area

Force/area= mass
