We report on the competition problems given at the 39th International Physics Olympiad held in Hanoi, Vietnam, which consist of three theoretical and one experimental problems. The abbreviated solutions are presented. The distribution of marks for the problems is also shown. (Contains 2 tables and 8 figures.)

Photographs illustrate several principles of physics which can be observed in everyday situations. (CP)

Lists several ideas for experiments for the amateur scientist to try or design. The list covers a wide range of topics; sound, mechanics, thermodynamics, fluids, optics, and electrostatics. (GA)

Presents experiments that use the Mattel's Hot Wheels Top Speed toy set to show that work is a measure of energy transferred to or from a system. (JRH)

This course of study is aligned with the California State Science Framework and provides students with the physics content needed to become scientifically and technologically literate and prepared for post-secondary science education. Framework themes incorporated into the course of study include patterns of change, evolution, energy, stability,…
