Describe how you would measure the acceleration of a trolley in an experiment.

To measure the acceleration of a trolley, I would set up a track and attach a force sensor to apply a known force. Using a stopwatch, I would measure the time taken for the trolley to travel a specific distance. I would then calculate acceleration using the formula a = (final velocity - initial velocity) / time taken.

This question assesses the student's ability to design an experiment and apply the concept of acceleration in a practical context. It requires knowledge of the relationship between force, mass, and acceleration, as well as the ability to perform calculations based on experimental data.
