Ahmed is testing how different objects accelerate based on their mass. He runs three tests and records the data shown below.

\begin{tabular}{ccc}
Test & Mass & Acceleration \\
\hline
1 & [tex]$5\, \text{kg}$[/tex] & [tex]$3.5\, \text{m/s}^2$[/tex] \\
2 & [tex]$7\, \text{kg}$[/tex] & [tex]$2.8\, \text{m/s}^2$[/tex] \\
3 & [tex]$15\, \text{kg}$[/tex] & [tex]$1.2\, \text{m/s}^2$[/tex]
\end{tabular}

Why might Ahmed's data be hard for other students to understand?



Answer :

Ahmed's data might be hard for other students to understand because the units for acceleration are incorrectly labeled. Here's a step-by-step explanation:

### Observing the Data:
Ahmed ran three tests and recorded the following data:
- Test 1:
- Mass: 5 kg
- Acceleration: 3.5 kg

- Test 2:
- Mass: 7 kg
- Acceleration: 2.8 kg

- Test 3:
- Mass: 15 kg
- Acceleration: 1.2 kg

### Correct Units:
In physics, mass is typically measured in kilograms (kg), and acceleration is measured in meters per second squared (m/s²). Observing Ahmed’s data, the acceleration units are labeled as kilograms (kg), which is incorrect.

### Correcting the Units:
Given the correct units for acceleration should be "m/s²", the data should be represented as:
- Test 1:
- Mass: 5 kg
- Acceleration: 3.5 m/s²

- Test 2:
- Mass: 7 kg
- Acceleration: 2.8 m/s²

- Test 3:
- Mass: 15 kg
- Acceleration: 1.2 m/s²

### Conclusion:
The error in labeling the units for acceleration as kilograms (kg) instead of meters per second squared (m/s²) could cause confusion for other students interpreting the data. Correcting these units will make the data clearer and easier to understand, aligning it with standard physics notation.
