Vertical and Horizontal Components of Velocity
For a projectile, in the absence of air resistance, the:
• horizontal component of velocity is constant
• acceleration is in the vertical direction and is the same as that of a vertically free-falling object.
The horizontal motion and the vertical motion are independent of each other: the constant vertical acceleration is independent of the horizontal speed.
The acceleration of a projectile, in the absence of air resistance, is in the direction of the gravitational force.
