When to use this calculator
Only the vertical velocity component contributes to the rise above the launch point.

PUTTING IT INTO PRACTICE
Projectile Maximum Height: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| Launch speed (m/s) | 20 |
| Launch angle (degrees) | 30 |
| Gravity (m/s²) | 10 |
| Result | 5 m |
- Check the input labels and enter the example values above.
- Apply the relationship: Maximum rise = speed² × sin²(angle)/(2 × gravity).
- The result is 5 m, rounded for display.
How to interpret your result
Does not add the starting height above the ground and ignores drag.
Choose a reference direction before using signed velocities. Constant-acceleration models do not capture variable braking or drag. Projectile tools explicitly state launch and landing assumptions.
Frequently asked questions
Are displacement and distance interchangeable?
No. Displacement is the signed or directed change in position; distance counts the length of the path travelled.
When is the projectile maximum height calculator useful?
Only the vertical velocity component contributes to the rise above the launch point.
How do I use the projectile maximum height calculator?
Enter launch speed (m/s), launch angle (degrees), gravity (m/s²). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Maximum rise = speed² × sin²(angle)/(2 × gravity).
What should I check before using the result?
Does not add the starting height above the ground and ignores drag.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
