Question 4

What is the Trolley Method Steps?

Answer 4

1) Set up your apparatus as shown in the diagram. Decide where you should place your light sensor to capture the final velocity of the trolley.
2) Carefully attach the timing card to the trolley and mark a start and finish point on the ramp, at least 1 m apart.
3) Set the ramp at an angle of 5°. If you place the ramp near the edge of the bench it is easier to measure the angles.
4) Release the trolley and use the stopwatch to time the trolley down the slope.
5) Use the light gate to measure the time taken for the trolley to pass through the light gate.
6) Repeat the experiment.
7) Increase the height of the slope and repeat the experiment.
