Projectile Motion Calculator
Fill in the values and the answer updates as you type.
How the Projectile Motion Calculator works
Splits the launch speed into horizontal and vertical parts and applies gravity of 9.80665 m/s². Air resistance is ignored, so real flights fall shorter. At level ground 45 degrees gives the longest range.
Inputs and results
The Projectile Motion Calculator takes 3 inputs and gives 3 results.
What you enter
- Launch speed (m/s) — starts at 20.
- Launch angle (degrees) — starts at 45.
- Launch height (m) — starts at 0.
What you get
- Horizontal range (m)
- Maximum height (m)
- Flight time (s)
Example: Projectile Motion Calculator with the starting values
With launch speed 20 m/s, launch angle 45 degrees and launch height 0 m, the calculator returns:
| Horizontal range (m) | 40.79 |
|---|---|
| Maximum height (m) | 10.2 |
| Flight time (s) | 2.88 |
Change any value above and the results update straight away.
Projectile Motion Calculator FAQ
How do I use the Projectile Motion Calculator?
Enter launch speed, launch angle and launch height in the fields, then read horizontal range (m), maximum height (m) and flight time (s) in the result panel. The answer updates as you type, and you can press Calculate or Enter to refresh it. Use “Copy link” to share your exact numbers with someone else.
What does the Projectile Motion Calculator calculate?
Range, peak height, and flight time of a launched object. It returns horizontal range (m), maximum height (m) and flight time (s) from the 3 values you provide.
What values does the Projectile Motion Calculator start with?
It opens with launch speed 20 m/s, launch angle 45 degrees and launch height 0 m so you can see a working result straight away. Replace them with your own numbers, or press Reset to return to these starting values.
Is the Projectile Motion Calculator free and private?
Yes. It is free, needs no account, and runs in your browser, so nothing you type is sent to or stored on our servers. See the Privacy Policy for details.
Can I rely on the Projectile Motion Calculator for important decisions?
Treat the result as a well-rounded estimate. Real situations often have details a general calculator cannot know, so confirm important decisions with a qualified professional. See the Disclaimer for more.
