Question
Wired Faculty App

A stone is thrown vertically upwards and then it returns to the thrower. Is it a projectile motion? Explain

Answer

The motion is not projectile because a projectile should have two component of velocities in two mutually perpendicular directions. But, in this case the stone has velocity only in one direction, while going up or coming downwards.
