As the mass of the object is increased, the force applied to the object increases to maintain the acceleration of the object.
The acceleration of the objects is determined from Newton's second law of motion as follows;
F = ma
a = F/m
a = 2/5 = 0.4 m/s²
a = 4/7 = 0.57 m/s²
a = 6/10 = 0.6 m/s²
Thus, from the data above we can conclude that, as the mass of the object is increased, the force applied to the object increases to maintain the acceleration of the object.
