Your result

Let’s calculate.

Use the Calculate button to see your result.

Review the method below for assumptions and conventions.

How to use this tool

  1. Enter launch speed, launch angle, gravitational acceleration.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Range = speed² × sin(2 × angle)/g.

A WORKED EXAMPLE

Using launch speed = 20 m/s, launch angle = 45 degrees, gravitational acceleration = 9.80665 m/s², the result is 40.7886485 m. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Ignores drag and Earth curvature. Launch and landing heights must match. An idealized educational model using the stated SI units. Real systems may need additional forces, losses or experimental measurements. Not a safety or equipment specification.

Common questions

Which inputs does this calculation need?

Estimate horizontal range for launch and landing at the same height. Enter launch speed in m/s, launch angle in degrees, gravitational acceleration in m/s². The filled example is editable and is not a saved personal record.

How should I interpret the result?

Ignores drag and Earth curvature. Launch and landing heights must match. An idealized educational model using the stated SI units. Real systems may need additional forces, losses or experimental measurements. Not a safety or equipment specification.
