About This Lesson
How can we make cars more efficient? Well, sometimes the easiest way to answer a question is to flip the question upside down: so, how can we make them less efficient?
The answer that Shannon and Kenny come across has to do with friction. An increase in friction means a decrease in efficiency… so, a decrease in friction means an increase in efficiency. (Remember the hovercraft?) Tags: Little Shop of Physics, Colorado State University, Physics, K-12, Brian Jones
