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 are the three methods of charging objects?
Friction Induction Conduction
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 are the differences between charging by induction and charging by conduction?
Charging by induction involves using an electric field to transfer charge without direct contact, while charging by conduction involves direct contact to transfer charge between objects.
What are the two ways to transfer electrical charges?
Friction - charging something by rubbing it against another object Induction - charging something by coming close to charged object, but not touching Conduction - charging something by touching a charged object
What is the difference between charging by conduction and charging by induction?
Charging by conduction involves direct contact between a charged object and a neutral object, transferring charge through direct touch. Charging by induction involves bringing a charged object near a neutral object, causing the charges to rearrange without direct contact.
3 methods of charging neutral objects?
Charging by induction: Bringing a charged object near a neutral object to create a separation of charges, leading to one side becoming positively charged and the other side negatively charged. Charging by friction: Rubbing two objects together to transfer electrons from one object to the other, causing one object to become positively charged and the other negatively charged. Charging by conduction: Directly transferring charge from a charged object to a neutral object by touching them together, allowing the charge to distribute evenly between the two objects.
What is the difference between charging by conduction and amp charging by Friction?
Charging by conduction involves transferring electric charge through direct contact between two objects. Charging by friction, also known as triboelectric charging, involves transferring electric charge by rubbing two objects together to create friction. Both methods result in the separation of charges, but the mechanism of charge transfer is different.
How do you discuss ways of charging a body?
To discuss ways of charging a body, you can explore methods such as friction, conduction, and induction. Friction involves rubbing two materials together to transfer electrons, while conduction involves direct contact between a charged object and a neutral one. Induction charges a body without direct contact by bringing a charged object close, causing a redistribution of charges. Each method has its applications and can be demonstrated through simple experiments or theoretical explanations.
Are the friction losses of an induction machine linear?
No, the friction losses of an induction machine are not linear. These losses are typically influenced by factors such as speed, load, and temperature, which can make the relationship between friction losses and operating conditions non-linear.
What causes electical charging of an object?
Electrical charging of an object occurs when there is an imbalance of electrons, leading to a buildup of either positive or negative charge. This can happen through friction, conduction, or induction, where electrons are transferred between objects, resulting in one object gaining excess electrons and becoming charged.
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 us the difference between charging by friction and charging by conduction?
Charging by friction involves transferring electrons between two objects by rubbing them together, causing one to become positively charged and the other negatively charged. Charging by conduction involves transferring electrons between two objects by direct contact, where one object has an excess of electrons and the other a deficit.
