What is projectile motion
A particle is thrown into air with an initial velocity and allowed to move under the influence of gravity
Projectile motion is the motion in which a body is thrown with some initial velocity with horizontal direction and then allowed to move in 2-dimensions under gravity alone.
Any object thrown in certain velocity and then allowed to move under the action of gravity ; is called projectile.
When a body is thrown at some angle with the horizontal with some speed and is able to freely fall then the motion of that body is called projectile motion
