Why does eraser became smaller when rubbed?
When an eraser is rubbed against paper, the friction between the eraser and the paper causes small particles of the eraser to break off. These particles stick to the paper, leaving a mark and making the eraser appear to shrink in size. This process is known as abrasion.
Why does our eraser get smaller and smaller as we use it?
As you use an eraser, the friction from rubbing it against the paper causes tiny bits of the eraser material to wear away and stick to the paper. This gradual erosion is what makes the eraser get smaller over time.
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.
What type of friction occurs when striking a match to light a fire?
The friction that occurs when striking a match to light a fire is kinetic friction. As the match head is rubbed against the rough surface of the matchbox, heat is produced due to the friction, causing the match to ignite and light the fire.
What happens when 2 surfaces are rubbed together?
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 is the word'rubbed'?
The word "rubbed" is the past tense form of "rub". The word rubbed means to have had two items causing friction against one another. For example, an eraser rubs out pencil marks. The friction from the eraser is what makes the writing disappear.

Would a rough surface have more or less friction than a smooth surface as you rubbed your hand across it?
more

When Eraser is rubbed with wool do it attract piece of paper?
When an eraser is rubbed with wool, it becomes charged with static electricity. This charge can attract small pieces of paper due to the phenomenon of electrostatic attraction. The rubbing action transfers electrons from the wool to the eraser, giving the eraser a negative charge, which then attracts the positively charged paper bits.
What the function and uses of eraser?
An eraser is a tool that is used to remove pencil marks from paper by rubbing it off. It is commonly used when making mistakes in writing or drawing to correct them. Erasers work by being rubbed against the pencil marks, creating friction that lifts the graphite from the paper surface.
What force is produce by rubbing two things together?
When two things are rubbed together, friction is produced. The force of friction occurs between the surfaces of the objects in contact and opposes the motion between them.
What causes a spark when rocks are rubbed?
friction
How is friction bad?
it can be harmful when rubbed against skin
