I need to bring something in school that will either decrease or increase friction?
do you have any ideas?
Answers:
They do sell these handy nylon pads that one sticks on the feet of chairs and tables to make them easier to slide across a floor or a carpet. They reduce the friction between the wooden feet and the floor.
They also sell rubber pads to stop the feet of chairs and tables slipping easily. They increase the friction.
You also have friction tape, as used by skateboarders on their boards or by people who put it along the top of a step so that people don't slide and fall. Its rough on the top like sandpaper and that increases the friction between the sole of the shoe and the surface that was slippery before it was taped.
I'd vote for the shoes idea. Very elegantly thought. For luck, you could bring a pair of shoes that you always slip in in the rain, and a pair of sport shoes with which you never slip. Gives you more to talk about, but just explaining the shoe and sock idea would be adecuate.
vaseline and sand.
oil decrease friction
any kind of lubricant to decrease friction (graphite lube, vaseline etc.)
anything rough would increase (sandpaper.
bring a rough table
oil decrease
1)Sandpaper-increase friction
2)Oil-decrease friction
water on a surface decreases the friction between 2 objects. Thats y when its rainnig, cars tend 2 slip and slide.
Muddy boots. it always causes friction in my house when I walk all over the carpet in muddy boots
Grease, oil, WD 40 will decrease friction
sand or dirt will increase friction (depending on the situation, these can also decrease friction- Like on a road when you are driving)
You can try a dry lube like powdered graphite and friction tape is good to increase friction.
A piece of rubber
Anything you put on top of your object will increase the friction since friction depends on the object's weight. Conversely, if you attach a helium balloon to the object the force of friction will decrease for the same reason.
k-y jelly
sex lube.decrease friction but increase friction between the teacher and yourself
Sandpaper and wax.
marbles sand paper also cornstarch will act like small ball berings bb's from also.
whats wrong with the shoe that your wearing? without the shoe on and only a sock between your foot and the floor, there is less friction and more chance of you sliding. with shoe on this increases the friction, making it easier to walk without sliding. provided you have good shoes with plenty of tread. so no need to carry anything extra to school ;)
hope it helps but bear in mind the teacher may think of this as a smarty panty answer.
If you want something that's handy - how about a mouse mat or a cheese grater?
bring an empty box. it is full of air which reduce friction in many applications such as trains,.
Teflon
A piece of resin as used by violinists on their bowstrings, this increases friction dramatically. And perhaps a piece of soap for the decrease.
