This site is a comprehensive reference archive covering the topics seen in introductory mechanics courses.
Target Student Population:
High school and lower-division undergraduate.
Prerequisite Knowledge or Skills:
High school algebra and trigonometry.
Type of Material:
Reference and supplement to textbooks.
An on-line reference for both instructors and students. Instructors who place homework assignments on the Web may find that links to the topic modules from within their problems are a useful instructional aid.
Evaluation and Observation
The overall coverage is quite comprehensive, systematic and illustrative. Numerous interactive examples are provided. Particularly noteworthy are those provided as illustrations for Newton's second law.
A few modules take give somewhat non-traditional explanations:
The discussion of variable acceleration includes a detailed module on the case where the acceleration can be expressed as a polynomial in time. This is not of great importance as most physicals systems do not behave in this way.
The discussion of Newton's second law states the law as F = ma and that the expression F = dp/dt is a special case of this. Most physicists view the latter equation as Newton's second law, and F = ma the special case.
This module states that F = ma does not work in the relativistic case where the mass of the object varies while elsewhere the author states (correctly) that relativistic mass is a concept that has limited utility and should probably be avoided in favor of relativistic equations for energy and momentum.
Potential Effectiveness as a Teaching Tool
The Hyperphysics site should be a highly useful supplement to any course. Both instructor and student can derive benefits from the site.
Ease of Use for Both Students and Faculty
The user interface is excellent. The concept maps are highly effective aids for finding topics quickly.
