This is directly related to Newton's Second Law of Motion, which states:
Force (F) = Mass (m) x Acceleration (a)
Let's break it down:
* Force (F) remains constant: You are applying the same force.
* Mass (m) decreases: The object is less massive.
* Acceleration (a) increases: To keep the equation balanced, if mass decreases, acceleration must increase to compensate.
In simpler terms, a less massive object is easier to move, so the same force will cause it to speed up more quickly.
