newtons law states F=ma so F/m=a in addition it makes logical sense the lighter an object the easier it is to accelerate its velocity form 0 to some quantity
Acceleration increases as mass decreases for a given force due to Newton's second law of motion, which states that force equals mass times acceleration. When mass is reduced while keeping the force constant, the resulting acceleration will be higher because acceleration is inversely proportional to mass. Thus, lighter objects accelerate more than heavier ones under the same force.
