Friction is affected by several factors. Here are the main ones for class 8th:

1. Nature of Surfaces: The amount of friction depends on the nature of the two surfaces in contact. If the surfaces are rough, the friction between them is high. If the surfaces are smooth, the friction is less.

2. Weight of the Object: The frictional force also depends on the weight of the object. If the weight is more, the friction is more and vice versa.

3. Surface Area in Contact: The frictional force is independent of the amount of surface area in contact. Whether a small area or a large area of an object is in contact with the surface, the frictional force remains the same.

4. Presence of Lubricants: The presence of a lubricant like oil or grease between two surfaces reduces friction. This is because the lubricant forms a thin layer between the two surfaces and they do not directly come in contact with each other.

5. Sliding or Rolling: Rolling friction is less than sliding friction. This is why it's easier to move a heavy object by rolling it (like a suitcase with wheels) than by sliding it.

6. Speed of the Object: At high speeds, the frictional force becomes less effective. This is why a car moving at high speed can easily skid if the brakes are applied suddenly.
