Slowing things down...

Now that you actually have a place to post a comment (oops!). Just describe any force (other than gravity) that you notice in the video. Try to include good details about what caused/created the force and what happened as a result of that force being applied.

Bonus; Does anyone want to try to explain why high-speed filming (shooting hundreds frames per second) makes the video look slo-mo during playback?
(FYI, this would be considered extra participation.)

Grounded for Life!!

Let's say that someone you know is driving WAY to fast on the freeway (obviously, you persoanlly are much too smart to do anything so foolhardy and dangerous!). Your friend's parents are going to see him driving at 80 mph no matter what. He can't escape getting busted! BUT, from the options below, choose which POV/frame of reference he would want his parents to have so his velocity seems the lowest relative to them.

Choose one by voting in the poll to the right, and add a comment to explain WHY your choice is best...

The parents driving 60 mph toward him (on the other side of the freeway, of course).

The parents driving 60 mph in the same direction on his side of the freeway.

Acceleration....Getting You Up to Speed

Thanks to our phenomenal photographers (Michael C., Rana, and Dean) and our outstanding demonstrators (Maddie, Rita, and Tyler) -- and to some clever engineering by Casio -- we were able to get three cool shots of a ball dropping.

So, what does it mean to accelerate?! There are four to five samples of the ball's location in each image. In your own words, respond to the two following questions:
1. What's different about the ball's velocity in at each point where it appears in the image?
2. Why is there more distance between each point where the ball appears in the image?
(Show me that you understand the concepts of velocity and acceleration by being detailed in your response.)

Phun Physics with Phelines...

Hope you all are cat lovers. I've always been more of a dog person, but there was no video called "Dun Dysics for Dogs." So, what did you learn from the video? Be detailed in your response...."I learned about friction" isn't the kind of response we're striving for.

Thanks for a strong first week, everyone. Have a nice and restful long weekend, and I'll see you soon.
