Overview
In horizontal projectile motion, an object is given an initial horizontal velocity and then moves under the influence of gravity alone (neglecting air resistance). Its horizontal motion is constant, while its vertical motion is that of free fall.
💡
Pro Tips
The time of flight depends ONLY on the launch height, not the horizontal velocity.
The range is the horizontal distance traveled until impact.
Final velocity is the vector sum of horizontal and vertical velocities at impact.
Assumes a flat ground and constant gravity (9.81 m/s²).

Fun Facts
"If you drop a ball and shoot a bullet horizontally at the same time, they will hit the ground at exactly the same time."
"The horizontal distance traveled is directly proportional to the launch speed."
"Real-world trajectories are slightly different due to air resistance, which this basic model neglects."
