Rowlands, Stuart; Graham, Ted; Berry, John – International Journal of Mathematical Education in Science and Technology, 1998
Reports on a small-scale investigation of student understanding of moments of forces to provide some indication as to the nature of intuitive ideas in this area. Results of the investigation suggest three stumbling blocks in the conceptual understanding of moment of forces. (Author/ASK)

Coutis, Peter – International Journal of Mathematical Education in Science and Technology, 1998
Presents the equations of motion governing the trajectory of a cricket ball subject to a linear drag force. Uses a perturbation expansion technique to solve the resulting trajectory equation for the range of a cricket ball struck into the outfield. (Author/ASK)
