projectile motion 1

• Projectile -Any object which projected by some means and continues to move due to its own inertia.
• Projectile Motion – is the motion of any object thrown into the air when, after the initial force that launches the object, the resistance is negligible and the only force acting on the object is the gravity, and its

  path is called trajectory.
• the initial horizontal velocity equals the final horizontal velocity
• Horizontally Launched Projectiles - Projectiles which have NO upward trajectory and NO initial VERTICAL velocity.
