The Horizontal Projectile Motion Calculator is a specialized physics tool that calculates the motion of objects launched horizontally from a height. This fundamental concept in physics helps understand projectile trajectories, predict landing distances, and analyze the independent nature of horizontal and vertical motion.
For more information about projectile motion and physics, visit Wikipedia: Projectile Motion and Wikipedia: Physics.
In horizontal projectile motion, an object is launched with only horizontal velocity from a height. The horizontal motion remains constant (no acceleration), while the vertical motion is affected by gravity, creating a parabolic trajectory path.
Horizontal and vertical motions are independent in projectile motion.
Whether you're studying physics, analyzing ballistics, designing projectile systems, or investigating motion principles, this calculator provides accurate trajectory analysis with comprehensive range and time calculations for educational and professional applications.

t = √(2h/g)
R = v₀ × t
v_final = √(v₀² + (gt)²)
Where h is height, g is gravitational acceleration (9.81 m/s²), v₀ is initial horizontal velocity, t is time of flight, and R is range.
Horizontal projectile motion calculations use the principle that horizontal and vertical motions are independent. The time of flight depends only on the height and gravity, while the range depends on the initial horizontal velocity and time of flight.
The calculator determines the time it takes for the projectile to fall to the ground, then uses this time to calculate how far horizontally the projectile travels. The final velocity combines both horizontal and vertical components using vector addition.
Launch Height: Initial vertical position above ground
Initial Horizontal Velocity: Speed in horizontal direction
Time of Flight: Duration until projectile hits ground
Range: Horizontal distance traveled
Final Velocity: Speed and direction at impact
The calculator automatically handles unit conversions and provides step-by-step solutions. It can determine range, time of flight, and final velocity for various launch conditions, making it valuable for physics education and projectile analysis in professional applications.
Given:
Step 1: Calculate time of flight
t = √(2h/g)
t = √(2 × 50 / 9.81)
t = √(100 / 9.81)
t = √10.19
t = 3.19 seconds
Step 2: Calculate range
R = v₀ × t
R = 10 × 3.19
R = 31.9 meters
Step 3: Calculate final velocity
v_final = √(v₀² + (gt)²)
v_final = √(10² + (9.81 × 3.19)²)
v_final = √(100 + 1000)
v_final = √1100 = 33.2 m/s
Final Answer
Range: 31.9 meters
Time of Flight: 3.19 seconds
Final Velocity: 33.2 m/s
Ball travels 31.9m horizontally in 3.19 seconds
Given:
Step 1: Calculate time of flight
t = √(2h/g)
t = √(2 × 200 / 9.81)
t = √(400 / 9.81)
t = √40.77 = 6.39 seconds
Step 2: Calculate range
R = v₀ × t
R = 150 × 6.39
R = 958.5 meters
Step 3: Calculate impact angle
v_vertical = gt = 9.81 × 6.39 = 62.7 m/s
v_horizontal = 150 m/s
θ = arctan(v_vertical / v_horizontal)
θ = arctan(62.7 / 150) = 22.7°
Final Answer
Range: 958.5 meters
Time of Flight: 6.39 seconds
Impact Angle: 22.7°
Package travels nearly 1 km horizontally before impact
🎯 Did you know? The range of a horizontal projectile is directly proportional to the initial horizontal velocity and the square root of the height. Doubling the height increases the range by √2 ≈ 1.41 times!
