When two surfaces are rubbed together, friction occurs, which generates heat and wear on the surfaces. This can lead to the production of small particles, called abrasion, on the surfaces being rubbed. If the surfaces are rough or have irregularities, they can interlock, causing the friction to increase and potentially creating damage.

What friction occurs when 2 solid objects are rubbed together?
When two solid objects are rubbed together, kinetic friction occurs. This type of friction opposes the direction of motion between the surfaces of the objects and is caused by the microscopic interactions between the surfaces. The rougher the surfaces and the greater the force pressing the surfaces together, the stronger the kinetic friction.
How does the force pushing 2 surfaces together effect friction?
The force pushing two surfaces together increases the friction between them. The greater the force pressing the surfaces together, the greater the frictional force that resists relative motion between them.
What can occur when 2 conductors are rubbed together?
When two conductors are rubbed together, they can transfer electrons between each other due to friction, which can create a buildup of static electricity. This can lead to a spark or a discharge of electricity if the charge becomes too great.
What are the 2 factors that affect the frictional force between 2 surface?
The two factors that affect frictional force between two surfaces are the type of material of the surfaces and the force pressing the surfaces together.
What 2 ways can friction between 2 surfaces increase?
Friction between two surfaces can increase due to an increase in the roughness of the surfaces or an increase in the normal force pressing the surfaces together. Additionally, an increase in the surface area of contact between the surfaces can also lead to an increase in friction.

What particle is transfered when 2 substances are rubbed together?
The outer surfaces of all substances encountered in our daily lives are covered in electrons. When two surfaces are rubbed against each other, electrons may be transferred from one surface to the other, creating a static charge on each of the substances, one positive and the other negative.
How does the force pushing 2 surfaces together effect friction?
The force pushing two surfaces together increases the friction between them. The greater the force pressing the surfaces together, the greater the frictional force that resists relative motion between them.

When two conductors are rubbed together, they can transfer electrons between each other due to friction, which can create a buildup of static electricity. This can lead to a spark or a discharge of electricity if the charge becomes too great.
How did the early man know that fire can be made?
they didn't know about it until a man rubbed 2 sticks together and made fire
What are the 2 factors that affect the frictional force between 2 surface?
The two factors that affect frictional force between two surfaces are the type of material of the surfaces and the force pressing the surfaces together.
What are two factors that affect tha friction force between two surfaces?
The coeffient of friction. The force holding the 2 surfaces together.
What 2 ways can friction between 2 surfaces increase?
Friction between two surfaces can increase due to an increase in the roughness of the surfaces or an increase in the normal force pressing the surfaces together. Additionally, an increase in the surface area of contact between the surfaces can also lead to an increase in friction.
What are the 2 factors on which magnitude of frictional force depends?
The magnitude of frictional force depends on the nature of the surfaces in contact and the normal force pressing the surfaces together.
How does friction make friction?
when 2 surfaces rube or slide together the more smooth the less friction
How does PVA glue stick wood together?
- PVA, white or yellow glue soaks into porous surfaces, then dries as it's carrier solvent evaporates. The substance left after evaporation has become hard and bonds the 2 surfaces together.
What are 2 variables that are involved with friction?
Two variables involved with friction are the nature of the surfaces in contact and the force pressing the surfaces together. The roughness or smoothness of the surfaces, as well as the weight or load applied on them, can affect the amount of friction generated.
