Inertia.
resistance (friction)
the amount of air resistance on an object depends on the size, shape, and speed of the object. Air resistance is the force that opposes the motion of objects through air.
This frictional resistance known as "air resistance" is the drag force. The drag force changes with the drag coefficient of the object in motion.
the object has less mass. the object has a large surface.

Inertia
The resistance of an object to changes in its motion is known as inertia. Changes in an objects motion include changes in its speed and direction.
Inertia is an objects resistance to change in motion. Frictional forces resist motion.

Resistance to the motion of an object is friction. Several different kinds of friction exist, including dry, fluid, lubricated, skin, and internal.
