Summary

Examiners reported that students demonstrated impressive knowledge of the electromagnetic spectrum, with most gaining all 3 marks in Q1(a). However, some students confused infrared and ultraviolet uses. In Q2, most students identified the centre of gravity and applied Newton's Third Law correctly, but some had issues with calculations and directions. Q3 was answered to a high standard, with students describing conservation of momentum well, but some made errors with units and equations. Q4 proved challenging, particularly Q4(a)(ii) and Q4(b)(ii), where students struggled to explain the origin of additional work and apply the correct formula. Q5(a)(i) was difficult due to scaling issues, while Q5(b) was answered exceptionally well. Q6 was completed to a high standard, with most students applying the formula correctly. In Q7, students recognized the need for opposing poles, but few understood the requirement for a uniform magnetic field, and many made errors in measuring the diameter of the path.
