Yes, it sure does! The more the weight (or mass), the higher the force of friction. Think of how hard it is to slide a 100 pound box across the floor versus a 10 pound box. Just getting it started (overcoming static friction) takes more force!
Oops- I meant SHOE experiment under friction…
We are doing the show experiment and are wondering if the weight of the show has an effect on friction. Should that be something we add to our data?
Well, after reading over this page, what did you figure out?
What is friction
Are there only 5 kinds of mechanic friction (i.e. Static, Kinetic, Dry, Fluid, & Skin )?
Just ‘friction’. Sometimes ‘dry friction’. 🙂
We were wondering what the friction between a liquid and solid is called (you mentioned the two solids= dry friction, and the two liquids= fluid friction). Also, is there friction between gasses and what is it called? thanks
Try clicking on the link above, waiting for a few minutes and then hitting ‘play’… does that help? Sometimes if the streaming-rate of the video is slower than the play-rate, you can hit a bump like this. Let me know if you still need help – use our Contact Us page so we can get right back to you.

We were listening to our first telecast on friction and all of a sudden it stops in the middle of a word – when you’re rubbing your hands together.
I’m assuming there’s more ?…………….
Bullets are hot because the friction between the air and the surface of the bullet heat it up… just like when you vigorously rub your hands together, they get warm. Same idea. 🙂
is this why bullets are hot when they hit someone?
Hmmm… looks like it works in IE but not Firefox. Let me see if our team can get that fixed…
it seems that the search bar on your site is not working. Is anyone else having a problem? Just wondering if it is my computer.

Hmmm… we just checked the link on this page and it seems to be working correctly:
