The three forces that causes an object to change its motion are the gravitational force, the normal force and the frictional force.

The direction of the force of friction is such that it opposes the direction of motion that an object would move if there were no frictional force acting on the object.
Kinetic
Yes, an unbalanced force is needed to change the motion of an object.If an unbalanced force does not act on an object it will continue to maintain its state of motion (either in motion or at rest), not considering the effect of frictional force. This is basically Newtons first law of motion.
Frictional force resists movement. In order to set an object into motion (or accelerate an already moving object), the force of friction must be overcome.

This frictional resistance known as "air resistance" is the drag force. The drag force changes with the drag coefficient of the object in motion.
false. Kinetic friction is the friction acting upon a moving object. It would be the frictional force against you if you pulled a box across a table. Static friction is the frictional force needed to overcome to get an object at rest into motion.
