Projectile Range Calculator

Enter your launch speed, launch angle, and initial height to calculate the horizontal range of a projectile. The Projectile Range Calculator returns the total distance traveled, maximum height reached, and time of flight — all based on standard kinematic equations with no air resistance.

m/s

The speed at which the projectile is launched.

°

Angle above the horizontal at which the projectile is launched. 45° gives maximum range on flat ground.

m

Height above the ground from which the projectile is launched. Use 0 for ground-level launches.

Frequently Asked Questions

What is the range of a projectile?

The range of a projectile is the total horizontal distance it travels from the launch point until it hits the ground. It depends on the launch speed, launch angle, initial height, and gravitational acceleration. Maximum range on flat ground (initial height = 0) is achieved at a 45° launch angle.

How do I calculate the range of a projectile?

For a launch from the ground, the range formula is d = (V₀² × sin(2θ)) / g. When launched from an initial height h, the formula becomes d = V₀cosθ × [V₀sinθ + √((V₀sinθ)² + 2gh)] / g. This calculator handles both cases automatically based on your inputs.

What angle gives the maximum range for a projectile?

When launched from the ground (initial height = 0), a 45° angle always produces the maximum range. However, if the projectile is launched from an elevated position, the optimal angle for maximum range is slightly less than 45°, depending on the height and launch speed.

Does the mass of a projectile affect its range?

No — when air resistance is neglected, the mass of a projectile has no effect on its range. The equations of projectile motion depend only on initial velocity, launch angle, initial height, and gravitational acceleration. This is consistent with Galileo's principle that all objects fall at the same rate regardless of mass.

What is the condition for minimum range of a projectile?

For a projectile launched from the ground, the minimum range (approaching zero) occurs at 0° (horizontal launch with no vertical component to keep it airborne) or 90° (straight up, so it falls back to the launch point). In practice, a very small or very large angle both reduce the range significantly.

How does initial height affect projectile range?

A greater initial height increases the time of flight because the projectile has more vertical distance to fall before hitting the ground. This longer flight time translates directly into a greater horizontal range, even at the same launch speed and angle.

Does gravity change the horizontal range of a projectile?

Yes — lower gravity (like on the Moon) increases range significantly because the projectile stays airborne longer. Higher gravity reduces range. This is why a ball thrown on the Moon would travel about 6 times farther than the same throw on Earth.

What assumptions does this projectile range calculator make?

This calculator assumes no air resistance, a flat Earth surface, and constant gravitational acceleration throughout the flight. These are standard assumptions for introductory physics problems. Real-world projectiles (especially at high speeds or long distances) are affected by drag, wind, and Earth's curvature.
