You might think it's all about weight, but actually it's about friction. Two kinds of friction! In today's episode of Crash Course Physics, Shini Somara tells us about Static and Kinetic friction; how they work and how they're different.

How the Brain Works Part 4 (UCLA)

How the Brain Works These brief videos provide an introductory appreciation of how we learn skills and information, move, think, feel, speak and remember. They are brought to you by the UCLA Brain Research Institute and by Bruce H. Dobkin, MD, who directs the neurorehabilitation program in the Department of Neurology at UCLA. The videos especially aim to reach out to students in grade school to stir their interest, and to people with disabilities in walking, using an affected upper extremity, and loss of memory from neurological diseases such as stroke, brain trauma, tumors, multiple sclerosis, cerebral palsy, Parkinsons, and Alzheimers disease.
