Question

How does the type of surface affect frictional force describe it with the help of a example​

Answer 1

Answer:

rough surface offer more friction while smooth surface offer less friction.

Step-by-step explanation:

hope it helped

Answer 2

Answer:

Friction occurs because no surface is perfectly smooth. Rougher surfaces have more friction between them. Heavier objects also have more friction because they press together with greater force. Friction produces heat because it causes the molecules on rubbing surfaces to move faster and have more energy.

Examples of frictional force

• Rubbing both hands together to create heat.
• A sled sliding across snow or ice.
• Skis sliding against snow.
• A person sliding down a slide is an example of sliding friction.
• A coaster sliding against a table.
• A washing machine pushed along a floor
