Here's the breakdown:

* 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.

Formula:

* F = ma

Where:

* F is the net force acting on the object (measured in Newtons, N)

* m is the mass of the object (measured in kilograms, kg)

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

Explanation:

* Direct Proportionality: A larger net force will result in a larger acceleration, given the mass remains constant.

* Inverse Proportionality: A larger mass will result in a smaller acceleration, given the net force remains constant.

In simpler terms:

* Force causes acceleration: If you push on an object (apply a force), it will start to move and speed up (accelerate).

* More force, more acceleration: The harder you push, the faster it will accelerate.

* Heavier objects accelerate less: If you push on a heavy object and a light object with the same force, the lighter object will accelerate more quickly.

Example:

Imagine you push a small car and a large truck with the same force. The small car will accelerate much faster because it has less mass.
