Strong Interaction: The Four Fundamental Forces of Physics #1b
There is a force stronger than electricity or gravity, so scientists named it the strong force. The video continues the explanation of the strong force and the way it works. It also describes the limitations, such as only working in very...

Downhill Science—Science of the Winter Olympics
Newton would have made a first-rate skier! A video lesson analyzes Newton's second law from a skiing perspective. The narrator explains how the force, mass, and acceleration can work together to create a winning run.
Veritasium
The Difference Between Mass and Weight
Why is it difficult to push a car? The video, produced by Veritasium, challenges people to answer this question scientifically. Then, a discussion of weight versus mass follows. Finally, it presents an answer and explanation highlighting...

Bozeman Science: Free Body Diagrams
Mr. Andersen shows you how to draw free body diagrams of various objects. The major forces (like gravity, normal, tension, friction, air resistance, etc.) are discussed and then applied to various problems.
Science for Kids
Science Kids: Sports Videos: The Physics of Skiing
Understand how force, acceleration, gravity, friction, and wind resistance all relate to the exciting sport of alpine skiing. [4:00]
Khan Academy
Khan Academy: Tension: Tension in a Accelerating System and Pie in the Face
The second part to a complicated problem. We figure out the tension in the wire connecting two masses. Then we figure our how much we need to accelerate a pie for it to safely reach a man's face. [9:28]
