Please I need a summary about the position and the motion

Motion is a change of position, which can be described in terms of the distance moved or the displacement. The motion of an object could be uniform or non-uniform depending on its velocity. The speed of an object is the distance covered per unit time and velocity is the displacement per unit time.

Position is the place where someone or something has been placed or put.

Motion is the state when an object changes its position with respect to a frame of reference with time.

here we know that ball will drop down by total distance 3.2 m

so here we know that

now using kinematics

now in the same time it will cover horizontal distance of 0.75 m

so speed of the ball will be
