Tips and Tricks on Motions In 2D


 


1
In projectile motion, the horizontal and the vertical motions are independent of each other, that is, neither motion affects the other.



2
The trajectory of a projectile will be parabolic when direction of velocity of projectile is different from direction of acceleration and its acceleration is constant both in magnitude and direction.



   3
If air resists or opposes the projectile motion then the projectile returns to the ground with less speed. At its trajectory its horizontal velocity also decreases.
