Friction involves two substances rubbing against each other. As this happens, one substance may lose electrons, thus becoming positively charged. Consequently, the other substance gains these electrons, becoming negatively charged.

When an insulator rubs against another material, it can cause electrons to be transferred from one material to the other due to the contact and separation forces. This results in one material becoming positively charged and the other becoming negatively charged. Friction between the insulator and another material can create an imbalance of electrons on the insulator's surface, leading to the insulator becoming charged.

Why is the laptop a good invention?
Laptops are a good invention because they are portable, allowing users to work or browse the internet from anywhere. They are also versatile and can be used for a variety of tasks such as work, gaming, or entertainment. Additionally, laptops have evolved to be powerful enough to handle most computing needs and have become an essential tool for many people in the modern world.
What happen if dented ping pong ball you put in ice water?
If you put a dented ping pong ball in ice water, the cold temperature may cause the air inside the ball to contract, intensifying the dent. Additionally, the change in temperature can affect the elasticity of the ping pong ball material, potentially making the dent more permanent.
Can bees see ultraviolet light?
Yes, bees can see ultraviolet light. Their eyes are sensitive to ultraviolet wavelengths, allowing them to see patterns on flowers that are invisible to humans. This ability helps bees navigate to food sources more effectively.
What is the scientific names of a Burning bush leaf?
The scientific name of the Burning bush plant is Euonymus alatus.
What is the scientific name for andeo virus?
The scientific name for Andes virus is Andes orthohantavirus. It is a type of hantavirus that can cause Hantavirus Pulmonary Syndrome in humans.
Why does a friction cause a charge to develop?
When an object such as a balloon is charged by friction, it is because electrons are rubbed off of one object onto another. The electrons only change their location, otherwise they remain the same.
How can an atom become positively or negatively charged by gaining or losing this subatomic particle?
Gaining or losing electrons can cause an atom to become positively or negatively charged
How may cleaning a mirror actually cause it to become more dusty?
because of the friction
What can friction cause?
It can cause things to stop. (===========================) friction did that
What happens to an atom's overall charge if it gains an electron?
since an electron is negatively charged, adding an electron to an atom will cause it to become negatively charged.
How do chemical reaction charge electrodes?
Chemical reactions occur between the electrolyte and the electrodes in an electrochemical cell. These reactions cause one electrode to become negatively charged and the other electrode to become positively charged.
What are ionized particles?
Ionised particles are particles that carry a positive or negative charge. This is due to the loss or gain of an electron or electrons. Losing an electron will cause a particle to become more positively charged, while gaining an electron will cause a particle to become more negatively charged.
How does an automobile use friction?
Friction is a cause of lost energy and inefficiency. But it is critically important to have friction as regards automobiles. The most important use of friction by vehicles is that involving their contact with the ground. Without friction, there would be traction, which would translate into no acceleration and no control of the vehicle. Think this through and it will become clear.
When there is no friction a gliding puck will what?
the friction will cause it to stop
If your headphones become magnetically charged and the ear pieces become attracted to each other is it still safe to use them or should you throw them away?
If your headphones become magnetically charged you should throw them away. This could cause significant problems with your ears and head.
How does friction affect your skin?
Friction of the skin can cause chaffing and chapping. The friction can cause bed sores in people that are bedridden, and irritation in people that are active.
Does friction decrease or increase?
Wax, due to it filling the pores that cause friction will reduce friction.
