Today we define Force. Really, such a simple concept and a word that pretty much everybody has used at some point. However, for a physics class, you need to fully understand what it means.
Introduction to Force
This was originally going to be part of "Do Your Feet Affect How Far You Slide on a Water Slide?", but it was too long. I used a 5 second clip instead. However, this was too much fun not to share.
I truly enjoyed filming this video. Rhonda Petty graciously agreed to open Rolling Hills Water Park an hour early so we could film. Aaron Fown used his quadcopter to provide aerial footage. My whole family helped with the filming. Lots of fun. All to answer the question, "Do Your Feet Affect How Far You Slide on a Water Slide?"
WiFi Through Water!
I discovered today that my iPhone can connect to my GoPro Hero Camera via WiFi even when the GoPro is in the water. How cool is that? (The iPhone is showing a live view from the camera at the bottom of the tank.)
A classic frame of reference example; riding a skateboard and throwing a ball. Thank you very much Chris Dupont for letting me use my recording of your show at The Ark in this video.
This video hits close to my heart because I have had this conversation with students on so many different occasions. The difference between understanding a concept and memorizing how to solve a problem.
What do you do if the velocity of the object with respect to the Earth is not the hypotenuse of the velocity tip-to-tail vector addition triangle?
Yep, I make physics videos in the hope that you can learn physics. If you are a physics teacher, I am very hopeful that you will want to use them to help flip your physics class.
