Example Data Table
| Mass | Initial Speed | Angle | Height | Gravity | Study Factor |
|---|---|---|---|---|---|
| 25 g | 180 m/s | 35 deg | 1.5 m | 9.80665 m/s² | 0% |
| 30 g | 150 m/s | 40 deg | 1.2 m | 9.80665 m/s² | 5% |
Formula Used
Horizontal velocity: vx = v × cos(θ)
Vertical velocity: vy = v × sin(θ)
Height at time: y = h + vy × t − 0.5 × g × t²
Distance at time: x = vx × t
Energy: E = 0.5 × m × v²
The model uses simple projectile motion. It ignores true air resistance, projectile shape, spin, weather, and surface effects. The drag field is only a classroom reduction factor for comparison.

Educational Projectile Motion Guide
Purpose
This calculator studies basic projectile motion in a safe way. It is made for classroom examples, homework checks, and general physics learning. It does not create aiming advice. It does not replace lab testing, professional training, or safety rules. The goal is to show how speed, angle, gravity, and height affect a moving object after launch.
Main Inputs
Initial speed controls how fast the object starts. A larger value usually increases travel distance and energy. Launch angle changes the split between horizontal and vertical motion. A higher angle may give more height, but it may not always give more range. Starting height adds extra time before the object reaches the ground. Gravity pulls the object downward during every step.
Energy Meaning
Energy is calculated from mass and speed. Mass is converted from grams to kilograms before calculation. The starting energy uses initial speed. The final energy uses the estimated speed near impact. These values help students compare motion cases. They should not be used for firearm setup or real world targeting.
Range and Height
The range shown by the calculator is an ideal physics estimate. It assumes a simple path and steady gravity. Real objects can behave differently. Air flow, shape, rotation, surface texture, and weather can all change movement. The simple study factor lets users reduce the displayed range for a rough classroom comparison, but it is not a real drag model.
Best Practice
Start with the example data. Change one input at a time. Watch how the table changes after each calculation. Compare the time, distance, height, speed, and energy rows. This method helps you understand cause and effect. Keep notes for each trial. Use the export buttons when you need a record for a report.
Limitations
The calculator is intentionally limited. It avoids field corrections, sight adjustments, zero range, wind calls, and weapon guidance. It gives a transparent motion estimate for education only. For any real safety matter, follow local laws, approved training, and qualified instruction.
FAQs
1. What does this calculator estimate?
It estimates time, distance, height, speed, and energy for simple educational projectile motion.
2. Is this for firearm aiming?
No. It is not for aiming, zeroing, hunting, field correction, or weapon adjustment.
3. Why is drag simplified?
True drag needs advanced data. This page only adds a basic study factor for classroom comparison.
4. What unit is mass entered in?
Mass is entered in grams. The calculator converts it to kilograms for the energy formula.
5. What does launch angle affect?
It changes vertical and horizontal velocity. That affects height, time, and estimated range.
6. Can I export results?
Yes. Use the CSV button for spreadsheet data or the PDF button for a printable report.
7. Why can real motion differ?
Real motion can change due to drag, shape, spin, wind, surface condition, and measurement error.
8. Who should use this page?
Students, teachers, and learners can use it for safe physics practice and motion comparison.
