Here's why:

* Newton's Second Law of Motion: This law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Mathematically: F = ma

* F: Force (measured in Newtons)

* m: Mass (measured in kilograms)

* a: Acceleration (measured in meters per second squared)

* Understanding the Equation: This means:

* More force, more acceleration: If you push harder on an object (increase force), it accelerates faster.

* Less mass, more acceleration: If the object has less mass, it accelerates faster with the same force applied.

Example:

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

In conclusion: Objects with less mass accelerate at a higher rate when the same force is applied to them. This is due to the inverse relationship between mass and acceleration, as described by Newton's Second Law of Motion.
