22M.1A.SL.TZ1.4

A.  v

B.  v2

C.  v2

D.  v4

Examiners report

With a lower difficulty index for SL candidates than for HL candidates, this question asked students to recognize the relationship between variables in a kinematics equation. For both groups, option C (incorrect) was most frequently selected, as candidates struggled to show the relationship between U and the change in frictional force. This question would be a useful teaching tool, as results here suggest candidates should spend more time working with equations without numerical substitutions.
