Outline, without calculation, the change to the time period of the system for the model represented by graph B when a is large.

[2]

Markscheme

time period increases ✓

 

because average ω «for whole cycle» is smaller

OR

slope / acceleration / force at large x is smaller

OR

area under graph B is smaller so average speed is smaller. ✓

Examiners report

Many candidates recognized that the time period would increase for B, and some were able to give a valid reason based on the difference between the motion of B and the motion of A. It should be noted that the prompt specified "without calculation", so candidates who simply attempted to calculate the time period of B did not receive marks.
