According to Newton's second law of motion, the acceleration of an object is directly proportional to the net force acting on the object and inversely proportional to its mass. Mathematically, it can be expressed as:

$$a = \frac{F}{m}$$

Where:

- a is the acceleration of the object in meters per second squared (m/s²)

- F is the net force acting on the object in Newtons (N)

- m is the mass of the object in Kilograms (Kg)

This means that if you increase the force acting on an object while keeping its mass constant, its acceleration will increase. Similarly, if you decrease the mass of an object while keeping the force constant, its acceleration will increase.
