In the absence of air friction, a projectile will follow a predictable parabolic trajectory determined by its initial velocity and launch angle. The projectile will continue to move freely in a straight line unless acted upon by an external force like gravity.
The horizontal component of a projectile's velocity remains constant in the absence of air friction. This means the projectile will continue to move horizontally at a constant speed unless acted upon by an external force.
The launch angle that results in the longest range for a projectile, in the absence of air resistance, is 45 degrees.
Air friction acts as a resistive force on a projectile, slowing it down and reducing its speed. This can cause the projectile to deviate from its intended path and fall short of its target as the air friction dissipates its kinetic energy. The magnitude of the effect depends on factors such as the projectile's speed, shape, and surface area.
A projectile will travel on a straight line unless external forces act upon it. Gravity will pull the projectile downward, i.e. affect its vertical velocity component. This is why the projectile will decelerate upwards, reach a maximum elevation, and accelerate back down to earth. The force vector of air resistance points in the opposite direction of motion, slowing the projectile down. For example, If the projectile is going forward and up, air resistance is pushing it backwards (horizontal component) and down (vertical component). Without air resistance, there is no external force acting upon the horizontal velocity component and the projectiles ground speed will stay constant as it gains altitude and falls back down to earth.
Without air resistance, the path of a projectile over a small part of the Earth's surface, under the influence of gravity alone, is always a piece of a parabola ... as long as it's not launched straight up or straight down.
The horizontal component of a projectile's velocity remains constant in the absence of air friction. This means the projectile will continue to move horizontally at a constant speed unless acted upon by an external force.

absence of friction...no air resistance
A projectile will travel on a straight line unless external forces act upon it. Gravity will pull the projectile downward, i.e. affect its vertical velocity component. This is why the projectile will decelerate upwards, reach a maximum elevation, and accelerate back down to earth. The force vector of air resistance points in the opposite direction of motion, slowing the projectile down. For example, If the projectile is going forward and up, air resistance is pushing it backwards (horizontal component) and down (vertical component). Without air resistance, there is no external force acting upon the horizontal velocity component and the projectiles ground speed will stay constant as it gains altitude and falls back down to earth.

The velocity of a projectile is considered to be constant when there is no change in speed and direction. This usually occurs in the absence of any external forces, such as air resistance or gravity, that could affect the projectile's motion.
Depending on the shape, speed and change in attitude (especially a tendency to tumble) of the projectile its losses of speed at various instants along its trajectory could be quite considerable owing to friction. Under many conditions air friction is proportional to the fourth power of speed. Thus, the horizontal component of the trajectory could be subject to considerable loss of magnitude. As one would expect the shape of the projectile will affect it's path considerably too.
In the absence of air resistance, mass does not affect the motion of a projectile. All objects fall at the same rate regardless of their mass in a vacuum. This principle is described by Galileo's law of falling bodies.
The optimal launch angle for the longest distance of a projectile is 45 degrees in the absence of air resistance. This angle allows for the greatest horizontal distance because it balances the vertical and horizontal components of the projectile's velocity.
The horizontal component of a projectile follows uniform motion, meaning it moves at a constant velocity in the absence of air resistance or other forces. This motion is independent of the vertical motion of the projectile.
