Explanation:
The term "center of the mass" of a system can be defined as the point on the system where the mass of the system is said to be concentrated. It is useful for linear or rotational motion.
Since the external force, since there is no air resistance, on the firework shell is zero, so the center of mass of the system will not move, it will remain at the same place.
When the fire work shell explodes, it means that it has a proper inelastic collision. Here the momentum will be conserved and not the kinetic energy.
Now if there is more air resistance force, there is an external force acting on the mass and therefore the center of mass will now shift.

Answer:
Conservation of mechanical energy
Explanation:
Law of Conservation of Mechanical Energy: The total amount of mechanical energy, in a closed system in the absence of dissipative forces (e.g. friction, air resistance), remains constant.
In the absence of air resistance, the mechanical energy of an object moving through the air in the Earth's gravitational field, remains constant (is conserved) while the opposite is the case when there is air resistance involved.
