I need help with this physics question.?
Ignoring air resistance everything on earth falls with acceleration 'g'. But the weight force is larger for more massive things. Use Newton's second law to resolve this. Explain.

From Newton's Laws:
"An object at rest tends to remain at rest;
or if in motion to remain in motion unless
acted upon by a force."
The force is mass × acceleration
The force of gravity is proportional to mass
but the resistance to change in velocity (Inertia)
In the absence of drag, all objects fall at the same rate.
Update if you need more, and please choose a best answer
from among those you get.

weight force W = grav. mass mg *grav. accel. g
accel. = weight force / inertial mass mi = mg*g/mi = g ..since mg and mi are equal and worth m
