These numbers are original invented classroom examples. Nothing was measured or quoted from a real provider. The cart readings are a simulation. Keep the table, units and fiction label together if you print or copy a card. The scatterplot frame, cost board and their text alternatives are available without a screen. Your teacher will supply separate check items later.
Card A · model cart readings
The model cart's mass is 0.50 kg. F_net means combined/net force. The acceleration values were invented to resemble repeated readings; they were not collected in a lab. No wheel finish was compared.
| Trial | Net force (N) | Simulated acceleration (m/s²) |
|---|---|---|
| 1 | 1 | 1.8 |
| 2 | 1 | 2.1 |
| 3 | 2 | 3.8 |
| 4 | 2 | 4.2 |
| 5 | 3 | 5.9 |
| 6 | 3 | 6.2 |
| 7 | 4 | 7.8 |
| 8 | 4 | 8.1 |
Use net force horizontally from 0–4 N and acceleration vertically from 0–10 m/s². Describe the pattern and what the table cannot test.
Card B · invented route pairs
Pairs are (route distance in km, listed duration in minutes): (2,7), (4,13), (6,18), (8,26), (10,31), (12,35). These are fictional, not transport advice or a prediction. Use distance horizontally from 0–12 km and duration vertically from 0–40 minutes.
Card C · invented adult device-hire plans
An adult fictional household is comparing two month-to-month plans for study and creative work. m is a number of complete months from 0–12. For the exercise, both plans are assumed to meet the same access, safety and service minimums and to have no exit fee; a real person would need to verify those claims. The practice cap is $1,000 for ten months. No family financial information is requested.
| Plan | Setup cost | Charge per complete month |
|---|---|---|
| A | $240 | $80 |
| B | $480 | $50 |
Write a cost rule for each plan. Compare the same number of months. Check both the total and the timing of payments, then name one missing real condition before making any real decision.
