Flipping Physics Posted May 21, 2014 Share Posted May 21, 2014 Name: A Basic Acceleration Example Problem and Understanding Acceleration Direction Category: Kinematics Date Added: 21 May 2014 - 08:53 AM Submitter: Flipping Physics Short Description: None Provided This video starts with a simple acceleration problem and then addresses a commonly held misconception that a negative acceleration always means you are slowing down. I do this by way of examples. Kate (my wife) drove the Prius with a camera suction cupped to the window and videoed me riding my bike several times. In the end I ended up with four different examples on the screen at once and 25 different video layers to describe it all. I am really proud about how well it worked. Enjoy.
