I agree with Kristen. A great, fun video that details what the world
would be without friction is an old Magic School Bus. I believe it is
called "Frictionless Sports". If you can get a copy, it is worth
watching.

Re: A World without Friction:

Here are some things I brainstormed:

Our world would be in chaos. We would not be able to drive, ride
bikes, walk etc. Friction allows us to grip with the ground so that we
can begin moving. If we were able to somehow move without friction,
stopping then would become an issue. Friction ensures that we will
stop. An object that is in motion tends to stay in motion unless acted
upon by a force. Without friction, we would continue moving until we
hit another massive object.

Finally, friction is essential to life on earth. One key type of
friction is air resistance. Without air resistance, we would no longer
have an atmosphere. Life cannot exist in a vacuum.

I hope that helps,

Kristen

I will look over my notes and get back to you on questions.
The only one that stumped me was - What would the world be like without
friction?

Good, I don't feel too behind. I will do some work in the next few
days
to catch up. So far, so good with me. I teach several of these
concepts so I feel very comfortable, how about you? I do have a
question, however. Since I am working on this alone, I am writing all
my response to questions (homework, discussion, etc) and I am planning
on sending this in as part of my journal. Is this acceptable? I am
doing this to show reflection in leu of a discussion with a group.
Let
me know what you think. Thanks!

I about in the same place - I think I'm up to workshop 4 already but
may have to re-review it because it has been a couple of weeks.

Hi Chris...glad to hear that we are in the same boat. I am getting a
late start but I am about to begin workshop 3. Where are you in the
process? I also teach physical science, as well as chemistry at the
middle school level. Glad to hear we can help eachother through the
process.

Jamie

yes, I am taking the workshop/course for credit and would like to
share/discuss thoughts about what I've learned with you.

Hello, my name is Jamie and this is my first workshop, and my first
time
using channel-talkforce. I am an individual taking the Forces and
Motion workshop and would like to connect with others to discuss the
activities. Please email if you are also an individual, or if there
is
a group I could share some thoughts with.

Thanks,
Jamie
