0625/62/O/N/25 © UCLES 2025 4 A student sets up a flexible track on the laboratory bench. The student investigates the motion of a metal ball as it rolls from rest down the track. The metal ball rolls down the track, up the other side of the track, and comes momentarily to rest at a height h above the bench before rolling back down again. Plan an experiment to investigate how one variable affects the size of this height h. The apparatus available includes: • flexible track • two clamps, bosses and stands to support the track • selection of metal balls. Fig. 4.1 shows how the flexible track is supported. h path taken by ball metal ball flexible track clamp stand Fig. 4.1 In your plan: • state the one variable you have chosen to investigate • list any additional apparatus needed • explain how to do the experiment • state the key variables to be kept constant • draw a table, with column headings, to show how to display the readings (you are not required to enter any readings in the table) • explain how to use the readings to reach a conclusion.

Show the answer and mark scheme
variable
MP1
valid variable which may affect h stated
apparatus
MP2
ruler/measuring tape and
additional apparatus to measure the independent variable (if not height of release or diameter of ball)
method
MP3
measure the independent variable and release the ball
MP4
measure h and repeat for a new value of independent variable
control variable
MP5
any significant variable appropriate to the independent variable
table
MP6
columns with units, for independent variable and dependent variable
conclusion
MP7
compare readings in the table to see if/how/whether a change in the variable produces a change in h
OR plot a (line) graph with axes specified
