This means:

* Direct Proportionality: A larger net force will produce a larger acceleration for the same mass.

* Inverse Proportionality: A larger mass will produce a smaller acceleration for the same net force.

Mathematically, this is expressed as:

F = ma

Where:

* F is the net force acting on the object

* m is the mass of the object

* a is the acceleration of the object

Therefore, according to the second law of motion, the acceleration of an object is proportional to the net force acting on it and inversely proportional to its mass.
