How is mass related to acceleration?

Acceleration has no relationship to mass.
Acceleration works in inverse proportion to mass.
Acceleration works in direct proportion to mass.
Acceleration works in variable proportion to mass.

Acceleration works in inverse proportion to mass. According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. This means that if the mass of an object increases, its acceleration will decrease, assuming the force acting on it remains constant. Conversely, if the mass decreases, the acceleration will increase.

What is the answer

Acceleration works in inverse proportion to mass.
