Motion data lab: a moto-taxi ride

A moto-taxi rider in Kigali records a short ride with a phone GPS app: start, steady speed, braking for a speed bump, and stopping at the stage. Use the data like a physicist and a road-safety officer.

🎯 Aim

To analyse the motion of a moto from speed–time data: find accelerations from gradients and distances from areas under the velocity–time graph.

You will learn to

  • Plot and read a velocity–time graph from real-style data.
  • Calculate acceleration as the gradient of a v–t graph.
  • Calculate distance as the area under a v–t graph.
  • Use your results to judge road safety (speed limits).

🧭 What to do

  1. Tap Play the ride and watch the speedometer and the distance posts.
  2. Look at the data table: speed is recorded every 2 seconds.
  3. In Analyse a part of the ride, choose t₁ = 0 s and t₂ = 10 s. Read the gradient and the area.
  4. Move the times to study the constant-speed part, the braking and the bump.
  5. Answer the investigation questions. Use 💡 Hint before 📘 Method.
  6. Write your conclusion and download your lab report.

📋 The data

Smoothed speed readings (m/s) every 2 s from a phone GPS app. Realistic data made for learning.

🧠 Investigate: answer from the data

Type your answer and tap Check. Use 💡 Hint first; open the method only when you are stuck.

📄 My lab report

Your report collects the aim, your data table, the graphs, your answers and your conclusion. It is made on your phone or computer: nothing is sent to anyone.

Check your conclusion

The moto accelerates uniformly at 1.25 m/s² for 10 s, travels at a constant 12.5 m/s (45 km/h), then decelerates at 1.5 m/s² before the bump. The gradient of a v–t graph gives the acceleration and the area under it gives the distance (about 550 m in 60 s). The rider was above the 40 km/h town limit for about 22 s.
