true
A change in velocity - for example, a motion when there was no previous motion - occurs if an unbalanced force is applied to an object.
ans: do you mean motion? motion is the meaning to move relative to something else, and it occurs (or is seen to be occurring) when two objects pass each other that have different velocities (not necessarily changing velocities). Without this, you would not be able to perceive motion at all. Motion doesn't mean speed has to change, as that relates simply to acceleration.
During uniform motion, velocity is constant, so there is zero acceleration. Non-uniform motion involves a change in velocity, which means there is acceleration. Accelaration is a change in velocity. A change in velocity occurs when a body slows down, speeds up, or turns (changes direction), or a combination of these.
Motion is the change in an object's position.
Motion occurs when there is speed. A change of speed is not required.
Motion occurs when there is speed. A change of speed is not required.
It is called uniform motion in a straight line.

motion occurs when an object changes its position relative to a reference point.
potential energy changes to kinetic energy
when two bodies change their positions with time, it's termed as motion and if the motion continues it may begin to have velocity,acceleration etc

Equilibrium
motion occurs when any object is acted on by a force
