Friction

The video tutorial explains the concept of friction, its role in stopping cars, and how it is influenced by factors like weight and surface properties. It discusses energy conversion to heat and introduces drag as a type of friction. The tutorial also covers air resistance and gravity's effect on falling objects, using Galileo's experiment to demonstrate these principles.

What happens to energy when an object slows down due to friction?

How do the results of Galileo's experiment with a hammer and a feather demonstrate the effects of air resistance?
