Does it include drag or spin?
No—this is the textbook vacuum solution. For drag or Magnus effects, use a dedicated trajectory simulator.

Use this companion guide beside the interactive calculator to make sure you understand the “why” behind every click. Each section includes the classroom explanation, student-friendly language, and quick practice prompts.
Before you start
Collect the data points listed below and double-check their units. Keeping an organized “givens” list is one of the fastest ways to reduce math errors and impress exam graders.

- ballistics
- trajectory
Detailed procedure
Step 1
Enter the launch speed (m/s), launch angle (degrees), and optional initial height.
Step 2
Adjust gravity if you need a different planetary body.
Step 3
Read the time of flight, horizontal range, peak height, and x-distance at the apex.
Teaching & troubleshooting tips
Can I use degrees greater than 90?
Angles must be between 0° and 90°. Negative angles represent downward launches; convert as needed.
