"The Mechanical Universe and Beyond" free online Physics course
link
This course was designed to provide the equivalent of a college freshman physics course, and was produced by CalTech in 1985.
Description from the website:
A video instructional series on physics for college and high school classrooms and adult learners; 52 half-hour video programs and coordinated books
This series helps teachers demystify physics by showing students what it looks like. Field trips to hot-air balloon events, symphony concerts, bicycle shops, and other locales make complex concepts more accessible. Inventive computer graphics illustrate abstract concepts such as time, force, and capacitance, while historical reenactments of the studies of Newton, Leibniz, Maxwell, and others trace the evolution of theories. The Mechanical Universe helps meet different students' needs, from the basic requirements of liberal arts students to the rigorous demands of science and engineering majors. This series is also valuable for teacher professional development.
The associated textbooks are not free, but are available used on Amazon. The 1985 student edition and solutions manual are likely the editions referred to in these videos, as the videos share a 1985 copyright. The 2008 edition is also available, but the solutions manual is not listed on amazon.
