Projectile Motion

   Projectile motion is a two dimensional motions with constant acceleration.  The motion of an object projected into the air at an angle. For examples, when you are kinking a soccer ball, throwing a baseball, or a long jumping. When a projectile is an object upon which the only force acting is gravity.


There is no acceleration in Vx, gravity is the acceleration in Vy.


         
             Path of a projectile projected at an angle with horizontal direction.




Component projectile velocities in x and y direction,the Vx stays the same and moving at constant speed.



Four Types of Projectile Promblems:


Type 1:


Type 2:




Type 3:


Type 4:
