Question

Explains the effects of friction

​

Answer 1

Answer:

When fluid layers are moving relative to each other, a type of friction occurs which is known as ‘fluid friction’. The internal resistance to the flow of fluids is termed ‘viscosity’; in simple terms, the viscosity is nothing but ‘thickness’ of a fluid.

Effects of Friction

• It produces heat, that helps in heating parts of any object or to warm ourselves.
• It also causes loss in power.
• It produces noise during any kind of operation.
• It’s because of friction that we’re able to walk, run, play, etc.

Answer 2

Explanation:

Friction is a force between objects that opposes the relative motion of the objects. ... When two objects are moving relative to one another, kinetic friction converts some of the kinetic energy of that motion into heat. You can feel the heat of kinetic friction if you rub your hands together.
