kinetic frictional
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.
Kinetic
If you apply force to an object, you accelerate it. If you apply the force in the direction that the object is moving, you speed it up. If you apply it in the opposite direction, you slow it down. If you apply the force in another direction than the object is moving in you will change the direction of the objects motion. The amount of acceleration is given by a = F/m where a is acceleration, F is force and m is the mass of the object.
A force is needed to move an object.
an object in motion will stay in motion unless acted upon by another force
static
static
kinetic frictional
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.

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.
The three forces that causes an object to change its motion are the gravitational force, the normal force and the frictional force.
This frictional resistance known as "air resistance" is the drag force. The drag force changes with the drag coefficient of the object in motion.
Kinetic
Friction is a force that always acts in a direction opposite to that of motion. So the frictional force does negative work on the velocity of an object ( thus reducing the speed of an object).
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.
