A projectile is an object upon which the only force is gravity. Gravity, being a downward force, causes a projectile to accelerate in the downward direction. The force of gravity could never alter the horizontal velocity of an object since perpendicular components of motion are independent of each other; vertical force does not effect a horizontal motion. The result of a vertical force acting upon a horizontally-moving object is to cause the object to deviate from its otherwise linear path

Horizontally Launched Projectiles

 

 

Anim'n of a Cannonball Launched from a Cliff

 

 

As the cannonball falls, it undergoes a downward acceleration This downward acceleration is attributed to the downward force of gravity which acts upon the ball In the absence of horizontal forces, there would be a constant velocity in the horizontal direction. In the animation, this is depicted by the fact that the horizontal velocity component remains the same size throughout the entire motion of the cannonball.
