Inertia.
Inertia of motion is the resistance mass has to motion. It also is the resistance in change in momentum. Momentum includes two things: velocity and direction. When an object changes its velocity, the momentum of the object resists the change. Also, when an object does change its velocity, its momentum is directly changed. In general, the inertia of motion is matter's unwillingness to change velocity or momentum.
The difference is due to inertia. Inertia is the resistance to a change in motion (acceleration). A more massive object will have greater inertia, and therefore a greater resistance to a change in motion, resulting in a slower acceleration. A less massive object has lower inertia, and therefore less of a resistance to a change in motion, resulting in a faster acceleration.
Inertia is an object's resistance to change it's state of motion or rest. Motion or rest depends on the observer's frame of reference.

Inertia is an objects resistance to change in motion. Frictional forces resist motion.

Inertia.
The extent of resistance to a change of motion is determined by an objects mass. The mass of the object is measured in kilograms.
It is a Newton.
