Which way do I turn the wheel again? Examine the physics behind backing up in a short, yet fun video. The narrator compares stable versus unstable systems, which are applied to driving forward or driving backward. Things get even more complicated when you add a trailer to the unstable backwards system.

• This video is hosted on YouTube

Pros

• Animations help learners visualize the movement and direction of the front and back wheels of the vehicle in the demonstration
• The narrator provides clear explanations of the course corrections drivers must make to compensate for the unstable system at work when backing up

Cons

• None
