What is Projectile Range Calculator?

Understanding Projectile Motion and Range

The Projectile Range Calculator is a specialized tool that calculates the horizontal distance traveled by a projectile from its launch point to where it hits the ground. This fundamental metric is essential for understanding projectile motion in physics and has applications in ballistics, sports, and engineering.

For more information about projectile range and ballistics, visit Wikipedia: Projectile Motion and Wikipedia: Ballistics.

In physics, projectile range depends on three key factors: initial velocity, launch angle, and acceleration due to gravity. The range formula shows that maximum range occurs at a 45-degree launch angle when air resistance is negligible. This principle is fundamental in understanding how projectiles behave under the influence of gravity and is essential for maximum height calculations and time of flight analysis.

Maximum range occurs at a 45-degree launch angle when air resistance is negligible.

Whether you're studying physics, analyzing ballistics, designing sports equipment, or simply understanding the physics behind projectile motion, this calculator provides accurate, instant results with flexible unit conversions to meet your specific needs.

How to Calculate Projectile Range

Step-by-Step Calculation Guide

Formula

R = (v₀²sin(2θ))/g

This formula calculates the projectile range by using initial velocity, launch angle, and acceleration due to gravity.

Initial velocity (v₀) is the speed at which the projectile is launched. It's measured in units like meters per second (m/s), kilometers per hour (km/h), or feet per second (ft/s). The initial velocity determines how fast the projectile starts moving.

Launch angle (θ) is the angle at which the projectile is launched relative to the horizontal. It's measured in degrees or radians. The launch angle significantly affects the range - 45 degrees typically gives maximum range in the absence of air resistance.

Unit Conversions

Velocity conversions:

  • 1 km/h = 0.2778 m/s
  • 1 mph = 0.447 m/s
  • 1 ft/s = 0.3048 m/s

Angle conversions:

  • 1 degree = π/180 radians
  • 1 radian = 180/π degrees

The projectile range is crucial for understanding how far a projectile will travel. The range formula shows that range is proportional to the square of initial velocity and depends on the sine of twice the launch angle. This relationship is fundamental in projectile motion analysis.

Examples of Projectile Range Calculation

Real-World Applications and Use Cases

Example 1: Basic Projectile Range

Given:

  • • Initial velocity: 20 m/s
  • • Launch angle: 30°
  • • Gravity: 9.81 m/s²

Step-by-step calculation:

Step 1: Calculate sin(2θ)

sin(2 × 30°) = sin(60°) = 0.866

Step 2: Calculate v₀²

20² = 400 m²/s²

Step 3: Apply the range formula

R = (400 × 0.866) / 9.81 = 35.3 m

Final Answer

35.3 meters

Projectile range

Example 2: Maximum Range at 45°

Given:

  • • Initial velocity: 25 m/s
  • • Launch angle: 45°
  • • Gravity: 9.81 m/s²

Step-by-step calculation:

Step 1: Calculate sin(2θ)

sin(2 × 45°) = sin(90°) = 1

Step 2: Calculate v₀²

25² = 625 m²/s²

Step 3: Apply the range formula

R = (625 × 1) / 9.81 = 63.7 m

Final Answer

63.7 meters

Maximum projectile range

Example 3: Range with Different Units

Given:

  • • Initial velocity: 60 km/h
  • • Launch angle: 60°
  • • Gravity: 9.81 m/s²

Step-by-step calculation:

Step 1: Convert velocity to m/s

60 km/h × (1000 m/km) × (1 h/3600 s) = 16.67 m/s

Step 2: Calculate sin(2θ)

sin(2 × 60°) = sin(120°) = 0.866

Step 3: Calculate v₀²

16.67² = 277.8 m²/s²

Step 4: Apply the range formula

R = (277.8 × 0.866) / 9.81 = 24.5 m

Final Answer

24.5 meters

💡 Did you know? The range formula shows that doubling the initial velocity quadruples the range — that's why powerful projectiles travel much farther!
