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 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.
Amber is a natural organic polymer that becomes electrostatically charged when rubbed, leading it to attract lightweight objects like feathers or paper bits through static electricity. This property is due to the amber's ability to gain electrons when rubbed, creating an imbalance of charge that causes it to repel other negatively charged objects.
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.
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.
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.
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.
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.
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
Amber
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.
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.
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.
Thales of Miletos is credited with discovering that rubbing amber with fur creates a static electric charge. He observed that after friction, the amber attracted small objects like feathers.
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.
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.
