This is directly related to Newton's Second Law of Motion, which states:
Force (F) = Mass (m) x Acceleration (a)
This means:
* Acceleration is directly proportional to force: If you apply more force, the acceleration increases.
* Acceleration is inversely proportional to mass: If you decrease the mass, the acceleration increases.
In other words, a smaller mass will experience a greater change in velocity for the same applied force.
Think of it like pushing a small car versus pushing a large truck. You'll be able to get the car moving much faster with the same effort because it has less mass.
