Something has to either be pushed or pulled by force.

"Acceleration" is the term used to describe motion whose speed, or direction, or both, are changing.
It certainly is necessary. Sometimes it may be implied - for example, in practice, quite often planet Earth is used as a frame of reference. But whether it is implied, or explicitly stated, you always need a frame of reference to describe motion, or position.
No. Friction is just necessary for controlling motion.
Galileo believed that it was necessary for a scientist to describe how things move (kinematics) before he can explain the causes of motion (dynamics).
The two factors that describe motion are thing. :)
Repetition of sounds that create a feeling of forward motion
Describe the three types of plate motion and the faults that are characteristic of each type of motion.
Motion = dPosition/dt
By the relative motion of neighbour objects
In simple motion can be described as the movement of any object.
