This is because of Newton's Second Law of Motion, which states:
Force (F) = Mass (m) x Acceleration (a)
Here's how it works:
* Force is constant: You are applying the same force in both scenarios.
* Mass decreases: The second object has less mass.
* Acceleration increases: To keep the equation balanced, if the mass decreases, the acceleration must increase.
In simpler terms: Imagine pushing a small car and then pushing a large truck with the same amount of effort. The small car will accelerate much faster than the truck because it has less mass.
