Trains can be made which levitate over a track by magnetic forces, so that friction is eliminated (except air friction), and the electrical power which produces the levitation force can also produce forward motion.
To electrify a metal object, you can connect it to a power source such as a battery or electrical outlet using wires. The electricity will flow through the metal object, making it electrified. Be sure to follow safety precautions when working with electricity.
Yes, metal objects can become charged by conduction if they come into contact with a charged object. If a charged object is connected to a metal object, the excess charge can flow through the metal by conduction, causing the metal object to become charged.
It is easier to lift a metal block or massive stone underwater because buoyancy helps to support some of the weight of the object. The water exerts an upward force on the object, reducing the effective weight that needs to be lifted by the person. In contrast, in air, there is no buoyant force to counteract the weight of the object, making it feel heavier to lift.
When you run on carpet, your body builds up an excess of static electricity. When you touch a metal object like a doorknob, which conducts electricity easily, the excess charge flows from your body to the metal object, creating a sudden shock. This happens because the metal object provides a path for the built-up static charge to escape.
It's important to touch the object to the metal rod and not the rubber stopper because metal is a good conductor of electricity, allowing any static charge to be neutralized. Rubber is an insulator, so it doesn't allow the charge to flow and can cause a buildup of static electricity on the object. This can lead to potential shocks or other hazards.
When you walk on carpet, you can build up a charge of static electricity. If you then touch a metal object, the charge will flow from you to the metal object because metals are good conductors of electricity. This transfer of charge is known as static discharge.

Electricity is not a metal; it is the flow of electrons. In static electricity, the particles in an object try to neutralize each other, which causes a shock when touched. Metals like copper are great conductors of electricity, and can be drawn in electrical wires.

Both are static electricity.

Electroplating is a process where a metal coating is applied to an object using electricity. It involves passing an electric current through a solution containing metal ions and the object to be plated. The metal ions are attracted to the object's surface and form a thin, uniform coating.
It's important to touch the object to the metal rod and not the rubber stopper because metal is a good conductor of electricity, allowing any static charge to be neutralized. Rubber is an insulator, so it doesn't allow the charge to flow and can cause a buildup of static electricity on the object. This can lead to potential shocks or other hazards.
Charging an earthed metal object would cause the charges to be quickly neutralized by the earth's conductor. Since the earth is a good conductor of electricity, any excess charge on the metal object would dissipate rapidly into the ground, preventing the object from holding a charge.
Metals are good conductors of electricity, so they do not hold onto static charges well. When a metal object accumulates static charge, the charges quickly flow through the metal and disperse, preventing the buildup of significant static electricity.
