Example Data Table
These examples show how different motion models produce distance values in practical physics scenarios.
| Method | Inputs | Distance | Use Case |
|---|---|---|---|
| Constant Speed | 72 km/h for 2 h | 144 km | Steady highway travel |
| Uniform Acceleration | u = 5 m/s, a = 1.2 m/s², t = 15 s | 210 m | Vehicle speeding up |
| Initial + Final Velocity | u = 12 m/s, v = 24 m/s, t = 18 s | 324 m | Average velocity method |
| Free Fall | u = 0 m/s, g = 9.81 m/s², t = 3 s | 44.145 m | Vertical drop estimate |
| Segmented Trip | 40 km/h for 0.5 h, 60 km/h for 1 h, 30 km/h for 0.25 h | 87.5 km | Multi-stage route |
Formula Used
The calculator supports several motion formulas so you can match the equation to the physical situation.
1. Constant Speed
d = v × t
Use this when speed remains constant during the entire motion.
2. Initial Velocity, Acceleration, and Time
d = ut + ½at²
Use this for uniformly accelerated motion with a constant acceleration value.
3. Initial Velocity, Final Velocity, and Time
d = ((u + v) / 2) × t
This uses average velocity when acceleration is constant over time.
4. Free Fall / Vertical Motion
d = ut + ½gt²
This mode assumes downward direction is positive and gravity stays constant.
5. Segmented Trip
d = (v₁t₁) + (v₂t₂) + (v₃t₃)
Use this when motion happens in separate stages with different speeds.

FAQs
1. What is the difference between distance and displacement?
Distance is total ground covered. Displacement includes direction and can be positive or negative. This calculator mainly reports distance magnitude and shows signed displacement when relevant.
2. Which method should I choose?
Use constant speed for steady motion, acceleration mode for changing speed, initial-final velocity for average motion, free fall for vertical movement, and segmented trip for multi-stage travel.
3. Can I use different unit systems?
Yes. You can enter speed, time, and acceleration in different supported units. The calculator converts everything internally before producing the final distance.
4. Why does the calculator show a negative displacement?
A negative displacement means the motion direction is opposite to the chosen positive direction. The total travel distance remains positive because distance ignores direction.
5. Does the graph update after every calculation?
Yes. Each valid submission generates a fresh distance-versus-time graph based on your selected method and input values.
6. Is free-fall mode only for Earth?
No. You can change gravity to another value. That makes the calculator useful for experiments, custom simulations, or comparing motion on different planets.
7. What happens in segmented trip mode?
The calculator adds the distance from three constant-speed stages. It is useful when travel speed changes across different sections of a route.
8. Can I export results for reports or homework?
Yes. Use the CSV button for spreadsheet-friendly data and the PDF button for a printable summary with key calculation details.
