Khan Academy's Introduction to Physics: An overview of Physics and its relationships with math and the other sciences.

PhET: Free interactive math and science simulations.

Physics World: Published by the Institute of Physics, Physics World communicates world-class research and innovation to the widest possible audience. 

MERLOT Physics Portal: A collection of educational resources for instructors and students of physics, focusing on open access and open source content that improves conceptual understanding and problem solving.

Veritasium is a channel of science and engineering videos featuring experiments, expert interviews, demos, and discussions with the public about everything science. Dr. Derek Muller is its creator. He completed a degree in Engineering Physics from Queen's University in Canada, and a PhD in physics education research at the University of Sydney.

In this video, Muller explains the physics of how trees absorb water from their roots to their topmost branches.

Walter Lewin's Lectures:
"Walter Lewin is best known for his captivating lectures on elementary physics, which he delivered as a professor at the Massachusetts Institute of Technology for several years." (From Gale in Context - Biography)

Lectures by Walter Lewin: This channel contains the complete Physics I: Classical Mechanics, Physics II: Electricity and Magnetism, and Physics III: Vibrations and Waves lectures as presented by Walter Lewin in the fall of 1999, spring of 2002 and fall of 2004.

In this video, Lewin puts his life on the line to demonstrate the conservation of energy. He explains why the sky is blue, why clouds are white and why sunsets are red.

"Ramamurti Shankar is the Josiah Willard Gibbs professor of Physics at Yale University. His research is in theoretical condensed matter physics, although he is also known for his earlier work in theoretical particle physics." (From Gale in Context - Biography and Wikipedia)

YouTube Channels:
