Step 1
State the measurements the student should make to complete the investigation.
Answer
To investigate how the mass of the trolley affects the maximum height, the student should follow these steps:
-
Measurement of Mass:
- Use a balance to measure the mass of the trolley. This measurement can be varied by adding weights to the trolley.
-
Measurement of Height:
- The vertical height, h, reached by the trolley can be measured with a ruler or a tape measure. A reference mark can be made on the track at the maximum height reached by the trolley to ensure accuracy in measurement.
-
Repeat Trials:
- Repeat the experiment multiple times for each mass to ensure reliability. By firing the spring several times with the same mass, the average maximum height can be calculated to improve data accuracy.
-
Recording Data:
- Record the mass of the trolley and the corresponding maximum height achieved in a table for analysis.
