1. Magnetism and Motion Experiment | Planning an experiment to investigate the relationship between the velocity of a trolley and the separation of magnets, including equipment setup, measurements, control variables, and data analysis.

2. Graph Interpretation and Gradient Determination | Finding the gradient of the best-fit line with absolute uncertainty, using graphical analysis for circuit parameters.

3. Electrical Parameters Calculation | Using graph results to determine the electromotive force (E) and resistance (Z), including uncertainty propagation.

4. Resistance Calculation for Specific Current | Predicting the resistance value needed to achieve a specified current based on experimental data.
