Explainprojectile motion ? How it works and what are the assumptions of a projectilemotion?

A projectile can be defined as an object which is thrown in air and moves under the influence of gravity only. The path followed by the projectile is called its trajectory. Some examples include: a bullet from a pistol, bounced basketball or cricket ball.
The terms associated with projectile motion are: time of flight, horizontal range or simply range, maximum height reached, velocity.

Time of flight= [2*initial velocity*sin theta]/g

Max height = [v^2* sin^2 theta]/2g
