Question

What is the difference between friction, conduction, and induction?​

Answer 1

Friction, conduction, and induction are all ways that heat can be transferred, but they work in different ways.

Friction is the transfer of heat between two surfaces that are in contact with each other. When you rub your hands together, the friction between them creates heat.

Conduction is the transfer of heat through a material. When you put a metal spoon in a hot cup of tea, the heat from the tea is conducted through the spoon to your hand.

Induction is the transfer of heat through a magnetic field. This is a bit more complex, but it's how things like electric stovetops work.

Answer 2

Friction, conduction, and induction are all physical phenomena that involve the transfer of energy from one object to another.

Friction is the force that opposes the motion of two objects that are in contact with each other. It is caused by the irregular shape and roughness of the surfaces of the objects, and it results in a loss of energy.

Conduction is the transfer of heat energy through a material from one molecule to another. It occurs when molecules in a material vibrate and collide with one another, and the energy is transferred from the hotter molecules to the cooler ones.

Induction is the process by which an electrical current is generated in a conductor when it is exposed to a changing magnetic field. It is based on the principle of electromagnetic induction, which states that a magnetic field can induce an electric current in a conductor.
