Projectile Motion is the motion of an object in two directions. The object is moving in the x-direction with zero acceleration and in the y-direction with a constant acceleration equal to ± g.
To simplify problem solving, three assumptions are made:
The motion of a projectile is analyzed by considering the horizontal component of the projectile's motion to be independent of the vertical component. If air resistance is neglected, the horizontal component of motion does not change meaning there is no horizontal acceleration and the projectile moves with a constant speed. The vertical component of the projectile's motion is affected by gravity and can be described by the equations for an object in free fall.
