Answer:
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. There are several types of friction: Dry friction is a force that opposes the relative lateral motion of two solid surfaces in contact.

Answer ⤵
- Friction is the resistance to motion of one object moving relative to another.
- It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces

How is friction created?
- Anytime two objects rub against each other, they cause friction.
- Friction works against the motion and acts in the opposite direction.
- When one object is sliding on another it starts to slow down due to friction.
- By rubbing them together we generate friction and, therefore, heat.
What is friction used for?
- Friction is a resistance force that slows down or prevents motion, it is necessary for many applications where you might want to hold items or do things and prevent slipping or sliding.
- Friction is used in car brakes, when we walk or climb a hill, making a fire, skiing down a hill, and more.
What are 5 examples of friction?
Everyday Examples of Sliding Friction
- 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.
- An iron being pushed across material.
