Say True or false
Every motion made by a vibratory object and then back to its start point is a periodic motion
In this question its not mentioned that the motion is made in equal intervals of time. Please answer the question and justify it ?!

Vibratory motion caused by a restoring force acting on it when disturbed from mean position and inertia is essentially periodic.
Without a restoring force, the to an fro motion may not be periodic.
IN A PROJECTILE MOTION WE TAKE MOTION IN A HORIZONTAL DIRECTION AS g=0 while in vertical motion as g=-9.8 meter / second square why?

Projectile Motion is an example for motion in two dimension. It can be studied easily by resolving into two components – The vertical motion is affected by gravity and the horizontal motion is not affected by gravity.
Therefore we take g=0 when we consider the horizontal component of motion as the projectile is not accelerated in the horizontal direction. The horizontal component of velocity remains constant through out its motion.
The following presentation will help you understand the concept better.
