a
velocity
b
inertia
c
force
d
acceleration

Answer 1

For the first question regarding the free-body diagram of a ball in free fall with air resistance, the correct choice is:

b a downward arrow to represent the force of gravity and an upward arrow to represent the force of air resistance.

For the second question about the tendency of an object to maintain its state of motion, the correct choice is:

b inertia.
