Objects intrinsically resist to be accelerated due its mass. A clear example would be kicking a soccer ball vs kicking a bowling ball. Last ball will resist much more to be accelerated than first one due its greater mass (intrinsic property).

What if we positionate in a inertial frame of reference in space? If we push both previous balls with the same force we will obtain different accelerations due balls' masses isn't it?

Objects intrinsically resist to be accelerated due to their masses. A clear example would be kicking a soccer ball vs kicking a bowling ball. The latter ball will resist much more to be accelerated than the first one due to its greater mass (intrinsic property).

What if we position them in a inertial frame of reference in space? If we push both previous balls with the same force we will obtain different accelerations due to the balls' different masses, isn't it?

I know it is a basic question but I would like to have a strong argument.
