To investigate how the distance a trolley has rolled affects its speed, this is the method:

1. Measure the length of trolley
2. Mark ( start, finish, mid-point ) line
3. Measure ( angle, distance, force ) ramp is to the ( horizontal, vertical ) and distance from start line to light gate
4. Place trolley on ramp and ( let go, push ) (do not push)
5. The data logger will record the time taken for the trolley to pass through the light gate and calculate the ( velocity, displacement, acceleration ) of the trolley as it passes through the gate.
6. change starting position and repeat ( 3, 1, 2 ) or more times
