Friction between the eraser and the surface creates heat and abrasion, causing the graphite particles from the pencil marks to stick to the eraser and be lifted off the paper. This process helps to remove the marks and erase them effectively.

Is erasing a mistake with an eraser a chemical reaction?

No, erasing a mistake with an eraser is not a chemical reaction. It is a physical process where the friction of the eraser removes the pencil marks from the paper.


What type of friction occurs when an eraser is rubbed across a sheet of paper?

The type of friction that occurs when an eraser is rubbed across a sheet of paper is sliding friction. The surface of the eraser rubbing against the paper creates resistance and generates heat, which helps in erasing pencil marks.


How is low friction useful in your life?

Friction can be very useful in your life. You need low friction when you ski. If you have high friction you cannot glide easily on the snow. You can also use low friction when you ice skate. If you have high friction you cant glide across the ice. When you use your laptop your keypad has to be able to glide. Some examples of high friction are erasing with your pencil, rubbing your hands together etc.


What can be used to reduce the effect of friction?

Using lubricants such as oil or grease can help reduce the effect of friction by providing a slippery surface. Additionally, using materials with lower coefficients of friction, such as Teflon or nylon, can help minimize frictional forces. Proper maintenance and keeping surfaces clean can also help reduce friction.


How do forces like friction help us?

Forces like friction help us by providing traction to prevent slipping or sliding. Friction also helps in controlling the speed of vehicles and stopping them when needed. In everyday activities, friction enables us to grip objects, walk, and even write.
