Final answer:
The relationship between force, mass, and acceleration is dictated by Newton's Second Law of Motion, which states that force equals mass multiplied by acceleration. An increase in force or decrease in mass results in greater acceleration, and vice-versa.
Step-by-step explanation:
The relationship between the force applied to the mass of an object and the object's acceleration is defined in Newton's Second Law of Motion. According to this law, the force applied to an object is equal to the mass of the object multiplied by its acceleration (F=ma). This means that if you increase the force applied, the acceleration increases, and if you decrease the force, the acceleration decreases. At the same time, if the mass of an object increases, the acceleration decreases, and vice versa. For example, it's easier and faster to accelerate a small car than a big truck with the same amount of force because the truck has more mass.
