What are the similarities between charging by induction and friction?

Drag, when referring to Air Resistance, is a type of friction. When an object flies, it comes in contact with air that it has to push out of the way. Since energy is always transferred (never created nor destroyed), the moving object loses some energy/force/velocity when rubbing against the passing air.
The frictions that we are more aware of are kinetic and static friction. Static friction is what holds an object in place when another force is acting on it. For example, when you have a book on a table and slope it, the book takes a bit to start moving. However, if you hold the table at a lesser angle and touch the book lightly, it will start to move. This is the difference between static and kinetic frictions.

How wireless chargers are working?
Inductive charging (also known as "wireless charging") uses an electromagnetic field to transfer energy between two objects. This is usually done with a charging station. Energy is sent through an inductive coupling to an electrical device, which can then use that energy to charge batteries or run the device. Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electrical current to charge the battery. The two induction coils in proximity combine to form an electrical transformer. Greater distances between sender and receiver coils can be achieved when the inductive charging system uses resonant inductive coupling.

Similarities between clutch and brake?
The lining used for both clutch and brake are very similar . they are both usually operated hydraulically The brake linings create friction in the wheels of the car to stop it when applied . The clutch on the other hand does the opposite when at rest the clutch produces maximum friction. when applied it releases that friction.

What i the similarities between charging by conduction and charging by induction?
conduction charging is a kind of charging that the electrical loud must plug in to a power source like electric city or power supply or an adaptor. but induction charging is a way to charging a electrical loud that in this way electrical energy induces to our load throw magnetic field
What is the difference between charging by conduction and induction?
Charging by Induction:- 1. No physical contact. 2. No exchange of charge. Charging by conduction:- 1. Two objects must be in physical contact. 2.Transfer of charge takes place. Difference between charging by induction and charging by conduction: Induction Conduction 1. In this process there is no physical contact between the objects. 1. The conducting surface is connected to a charged object to transfer the charge. 2. The net charge on the object is zero since equal amount of opposite charge is accumulated on the side away from the side where a charge is induced. 2. The net charge on the object changes after the charging process since there is a transfer of charge.
Three methods to charge an object?
Charging by friction - this is useful for charging insulators. If you rub one material with another (say, a plastic ruler with a piece of paper towel), electrons have a tendency to be transferred from one material to the other. For example, rubbing glass with silk or saran wrap generally leaves the glass with a positive charge; rubbing PVC rod with fur generally gives the rod a negative charge. Charging by conduction - useful for charging metals and other conductors. If a charged object touches a conductor, some charge will be transferred between the object and the conductor, charging the conductor with the same sign as the charge on the object. Charging by induction - also useful for charging metals and other conductors. Again, a charged object is used, but this time it is only brought close to the conductor, and does not touch it. If the conductor is connected to ground (ground is basically anything neutral that can give up electrons to, or take electrons from, an object), electrons will either flow on to it or away from it. When the ground connection is removed , the conductor will have a charge opposite in sign to that of the charged object.
What is the difference between charging by contact and charging by induction?
It normally requres two coils of wire placed close to each other. The AC field on one will induce an AC field in the other. More chargers of portable equipment are using this method. It requires no physical contact, so reduces problems of poor contacts and can make the item more water proof.
What is charge by induction?
Charging by Induction is a method of charging a neutral object, using a charged object, without establishing physical contact between them. _______________________________________________________________________ When a charged object induces a charge on another object without touching it.

What are the hazards of charging by friction?
Potential hazards of charging by friction 1. Fuelling a plane with highly flammable high octane aviation fuel. The friction between the fuel and the pile and between the rubber fuel pipe and the drum as well as between the tyres of the refuelling truck could lead to a build up of charge. The truck, pipe and fuel delivery system are all earthed. 2. Cars get charged up and you can get a spark from them when getting out. This is due to friction between the tyres and the road. It can be prevented by small rubber strip with a centrepiece of metal fixed to the back of the car which rubs on the road and so discharges the car.
