Friction strips electrons so the rubbed amber would take on a negative charge. Actually, friction causes charges to shift. Charges are indeed stripped from something, but they are collected up by something else. Amber does, indeed, become negatively charged by rubbing it with, say, fur. The phenomon is called triboelectric effect. And a link is provided.

The earliest known records describing electric charge involve the use of?
The earliest known records describing electric charge involve the use of amber, a fossilized tree resin. Thales of Miletus, a Greek philosopher from around 600 BC, was among the first to document that amber could attract lightweight objects when rubbed.
What caused the amber to repel other objects when not rubbed?
Not all objects became electrified, objects "electrified" by the same machine appeared to repel each other (like magnets of the same charge); and objects "electrified" in different ways (one by touching an electric machine, for example, and the other, say, by rubbing amber) would attract each other (like magnets of opposite charge).
What happened when Thales rubbed amber with silk?
When Thales rubbed amber with silk, he observed that the amber attracted small objects like feathers and hair. This phenomenon is known as static electricity, where the friction between the amber and silk causes the transfer of electrons, giving the amber a temporary charged property.
What would happen if you rubbed a piece of fluorite a piece of feldspar?
If you rubbed a piece of fluorite against a piece of feldspar, neither mineral would really change. Both minerals are relatively hard and have different chemical compositions, so they would not interact in a way that would result in a noticeable reaction.
Can polythene rubbed against steel spoon produce charge?
Yes, when polythene is rubbed against a steel spoon, the two materials become charged due to the transfer of electrons between them. The polythene gains a negative charge, while the steel spoon gains a positive charge.
What charge does amber get when rubbed with nylon?
Amber becomes negatively charged when rubbed with nylon. This is due to the transfer of electrons from the amber to the nylon, leaving the amber with an excess of electrons and thus a negative charge.
Who was the ancient Greek scientist who discovered the fact that when a piece of amber was rubbed with fur it produced a charge which could attract light objects like feather and straw?
The ancient Greek scientist who discovered this phenomenon was Thales of Miletus. He observed that amber could generate static electricity when rubbed with fur, leading to the attraction of light objects like feathers and straws.
What happened when thale rubbed the amber with silk cloth?
when amber is rubbed with silk cloth +ve charge comes on silk cloth and -ve on amber due to interaction between their molecules, so is that when we comb our hairs , then -ve charge comes on comb and +ve on hairs,so when we bring silk cloth near the comb they attract each other due to 'ving opposite charges
What Thales rubbed with silk?
Amber
What happened when Thales rubbed the amber and the silk cloth?
Thales of Miletus, a Greek philosopher, discovered that rubbing amber with silk created an electric charge in the amber which caused objects to be attracted to it. If rubbed enough, it created a spark, much like we receive when we walk on carpet and touch a doorknob and see, hear and feel the spark.
Amber was used by the greeks to study what?
The Greeks used the amber to study the concept of magnetism for the first time . They observed that it acquires a strange property of attracting tiny bits of papers,metal pieces etc. when rubbed with a piece of wool .this strange characteristic of it made the further discoveries possible.+++That's not magnetism but static electricity, the charge being developed by rubbing the amber with the dry cloth. Amber is non-magnetic.
How did the thales experiment produce static electricity?
The Thales experiment involved rubbing a piece of amber with fur, which transferred electrons between the two materials creating an imbalance of charge. This process of friction generated static electricity on the amber, leading to the observation of electrical attraction when the amber was brought near small objects.
What did Thales of Miletos do to create a static electric charge?
he rubbed amber and it could pick up pieces of sticks, fur, wool or straw!
Why does a straw attract another straw when rubbed with piece of paper but repels it if it is rubbed with a sheet of paper?
When a straw is rubbed with a piece of paper, it acquires a positive charge due to the transfer of electrons from the paper. Two positively charged straws will repel each other. However, when a straw is rubbed with a sheet of paper, it acquires a negative charge, and opposite charges attract, resulting in the straws being attracted to each other.
Why is Electricity called Electricity?
It comes from the Greek word "electron." However, to the Greeks that word didn't mean what it does to us; it meant the material we call amber. It's called that because one of the first noticed electrical phenomena was that if you rubbed a piece of amber with a cloth you could build up a static charge and make a small spark.
