If you rub a coin briskly between your fingers it will not seem to become charged by friction. Why?

Why wouldn't i be able to pick objects up without friction?
They would slide off from between your fingers. No friction = no grip.
What happens when we touch a charged electroscope with our fingers?
The leaves would come closer than earlier
Why do people lick their fingers when they are picking up sheets of paper?
Dry fingers sometimes cannot separate sheets of paper because they just slide on the top sheet. Damp fingers create friction and adherence to the top sheet enabling you to separate it from the next one down.
Do heavier objects experience more friction?
Yes, heavier objects do experience more friction. This is because since they are heavier, it means more gravity is pushing down on the object. Because there is more gravity on the object, it pushes on the ground harder than other objects. This increases the friction on the object. It would be like you rubbing your fingers together softly. Your finger slides easily, right? If you push down harder, it becomes harder for your fingers to slide. It is the same principle, but just on a larger scale.
What is example of useful friction?
Friction can be very helpful. It prevents things from slipping away from your hand easily. Stopping a car from crashing (breaks). Slows you down when necessary Makes us able to stand up. Helps us sand things when doing wood projects (with sandpaper). Makes us able to carry things. You can also warm your body by friction by rubbing your hands together or on certain body parts to warm yourself up.
How do you remove oil stains from leather?
Rub Corn starch (or in a pinch, talcum powder) briskly into the stain with your fingers until the heat from the friction is felt. Vacuum or brush the powder off.

Why do your fingers have friction ridges?
Your fingers have friction ridges so that we can grab or catch or even hold things with our fingers. If we did not have these friction ridges then probably we wouldn't be able to hold things without the help of our fingers.
What makes you able to snap your fingers?
Pressure and friction
What causes blisters on hand palms and fingers?
Heat, friction and infection
What is a friction head massage?
its when the fingers go up in down in a small area too cause friction against your head
Is it a birth defect if you can't snap?
By snap I assume you mean snapping your fingers, if that's the case, the answer is no, the sound generated from your fingers are caused by friction and when you fail to make a sound it just indicate that there is insufficient friction, thus it is just a technique that not perfected!
Do gels kill Swine Flu?
The sanitizing hand gels that are at least 60% alcohol are very effective against the A-H1N1/09 virus. If hands are very soiled, wash with soap and water first if possible. Follow the label directions. Rub hands together with the gel between fingers and all over briskly since friction is also effective in physically removing the virus particles from your hands. Continue rubbing hands together until completely dry.

Why do moving objects on earth always experience friction while objects in outer space usually do not?
Friction is caused by the movement against anything, including the atmosphere, which grows thinner and thinner as you leave the planet. (It is also why planes fly so high in altitude - less friction means greater miles per gallon of jet fuel.) As an experiment, part your fingers such that there is air (or space) between them all; then run your wrist either side to side or forward and backward very rapidly so that you will feel the friction of the air against your fingers. This cannot happen in a vacuum of space, not that you could even attempt it.

Why do the two fingers get to the middle of the meter stick at the same time?
There is feedback mechanism going on all the time the fingers are moving. Friction between the fingers and the wooden stick is proportional to the weight of the stick at the point above the fingers. If the right hand finger moves towards the centre it reduces the weight directly above the left finger because there is now more wood to the right of the right finger. The decrease in friction above the left finger causes it to slip and move towards the centre. The process is now reversed and the right finger now starts to move. The two fingers end up at the centre of mass of the stick by an unseen oscillation of moments.
