Friction, is a force between two surfaces that are either sliding or rubbed together. Sliding friction in everyday life: -A sled on snow or ice -Cup being pushed along the table -Two books pushed together in a bookshelf -A chair leg sliding along the floor
When you ski on grass there is a lot of friction you cannot ski on it. However, if you ski on snow there is not a lot of friction, that's why the ski's move faster. On ruff surfaces there is friction and on smooth surfaces there is much less friction. Shoes, have rubber on the bottom because, if there was fabric it would be slippery (Less friction).
Friction is a force between two surfaces that are sliding, or trying to slide, across each other. For example, when you try to push a book along the floor friction makes this difficult.Friction always works in the direction opposite from the direction the object is moving, or trying to move. Friction always slows a moving object down.The amount of friction depends on the materials from which the two surfaces are made. The rougher the surface, the more friction is produced. For example, you would have to push a book harder to get it moving on a carpet than you would on a wooden floor. This is because there is more friction between the carpet and the book than there is between the wood and the book.
Examples of friction in daily life:
When cold, you rub your hands together to warm your hand.
Friction always works in the direction opposite from the direction the object is moving, or trying to move. Friction always slows a moving object down.

Friction is a force between two surfaces that are sliding or trying to slide across each other.
In other words friction is the resistance that one surface or object encounters when moving over another.
3 types of Friction
1. Dry Friction – occurs when 2 solid objects touch each other. If they not moving its called Static Friction and if they are moving tis called Kinetic Friction
2. Fluid Friction – involves fluid or air – e.g. air resistance on plane and water resistance on a boat
3. Rolling Friction – occurs when a round object rolls over a surface; e.g. like a ball or a wheel
Examples of friction in day to day life
I. Driving a car – tyre and road II. Swimming – water and swimmer III. Driving a trolley in supermarket – wheels of trolley and ground IV. Rubbing your hands V. Walking - Your feet and floor VI. Writing – holding a pencil and between lead and paper
1. Lived in big houses. 2. As glass was expensive rich people would have many windows to show how rich they were. 3. They would make money from selling crops from land which they owned. 4. The crops would be grown by farmers that in exchange got to live on the farm. 5. The rich would eat lots of meat, but only a few vegetables. They would also eat spices and sugar which the poor couldn't afford. Rich and poor Tudors ate very different food from each other. Vegetables which grew underground were only considered fit for the poor. 6. The rich men wore white silk shirts that were frilled at the neck and wrists. 7. Rich Tudor women wore silk stockings.
Life of Poor People in Tudor Times
1. Everyone in Tudor times ate bread but poor ate coarse bread of rye. 2. Poor people wore simple, loose-fitting clothes made from woollen cloth. 3. Poor would often work in farmlands. 4. Poor children had to work to earn money so they couldn't go to school as they had work to do. 5. The poor’s houses were made out of wattle, daub and thatch. 6. The homeless would get punished. 7. Poor people were often looked after by nuns or monks. 8. Some rich people donated money to build almhouses for the poor to live in.
DEFINITION: the force that slows you or an object. EXAMPLES: when a car is skidding on ice their isn't much friction. But when a car is stuck in the mud, their is a lot of friction. or, when your going down a slide, there isn't much friction at all. But when you sliding down a slanted gravel path there's heaps of friction.
Friction is the opposite force,that stops the movement. Here are some examples. * So if there was Grass on a Hill you are creating friction. *When you are driving you are creating friction. *If you have Sand Paper , rubbing on the wall it creates friction.
Friction is a force between two surfaces that are sliding, or trying to slide, across each other.Friction always slows a moving object down. Air resistance is a type of friction. When you are trying to push a book on the floor friction makes this difficult.Friction always works in a direction opposite from the direction the object is moving.Friction slows down a object from moving. The amount of friction depends on the material from which the two surface.
Friction is a force that stops things from moving easily. Whenever an object moves or rubs against another object, it feels frictional forces. These forces act in the opposite direction to the movement. Friction makes it harder for things to move. In the illustration below, the smooth base of the snow lades slides smoothly on the snow. The boy on the grass is having difficulty sliding, because the grass is not smooth and his shoes are getting stuck in the grass. There is more friction between the shoes and the grass than the snow and the snow blades.
Balance forces are two forces acting in opposite directions on an object, and equal in size. Anytime there is a balanced force on an abject, the object stays still or continues moving continues to move at the same speed and in the same direction. It is important to note that an object can be in motion even if there are no forces acting on it. Balanced forces can be demonstrated in Hanging, Floating and Standing/sitting objects. Every object is made up of matter (Matter is anything you can touch physically) The more matter an object has, the bigger it is, and the more mass it has. Mass is measured in kilograms, kg, or grams, g. Things that have a big mass are harder to move, or harder to stop than objects with little mass.

Heat Friction also produces heat. If you rub your hands together quickly, you will feel them get warmer.
Friction can be a useful force because it prevents our shoes slipping on the pavement when we walk and stops car tyres skidding on the road.
When you walk, friction is caused between the tread on shoes and the ground. This friction acts to grip the ground and prevent sliding.
A shoe tread Ice causes very little friction, which is why it is easy to slip over on an icy day. However this is a good thing for ice skating and sledging.
Reducing friction Sometimes we want to reduce friction. For example, we use oil to reduce the friction between the moving parts inside a car engine. The oil holds the surfaces apart, and can flow between them. The reduced friction means there is less wear on the car's moving parts, and less heat produced.
Air resistance
Air resistance is a type of friction between air and another material. When an aeroplane flies through the air, for example, air particles hit the aeroplane, making it more difficult for it to move through the air.
Illustration showing the forces of thrust and air resistance acting upon an aeroplane Some shapes, known as streamlined shapes, cause less air resistance than others. Aeroplanes and cars are streamlined, so that they move through the air as easily as possible.

1. An example of friction is when our feet walk on the floor. If there is no friction between your shoes or feet and the floor you would slip. 2. You rub your hands together to warm your hands when it is cold. The heat comes from friction. 3. Friction force is used to stop your car and bike when you use the breaks. If there was no friction between your tyre and the ground the car would be skidding everywhere 4. A person sliding down a slide is an example of sliding friction. 5.Other examples of sliding friction would be an iron being pushed across material. 6. Putting clothes on your skin. 7. Brushing your teeth. 8. When you sweep the floor. 9. When you use a pen to write. 10. When we open and close drawers.
Friction Friction is a force between two surfaces that are sliding, or trying to slide, across each other. Friction always slows down a momentum of a moving object. Air resistance is a type of friction. Here are some examples of 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 - A coaster sliding against a table - A washing machine pushed along a floor.
Friction also produces heat. When you rub your hands together you can feel them getting warmer.
More or less friction The amount of friction depends on the materials of which the two surfaces are made. The more rough the surface, the more friction is needed. For example you would have to push harder on a toy car on the carpet than you would do with a wooden planked floor. This is because more friction is needed because the carpet is a rougher surface.

Friction is a force that holds back the movement of a sliding object.You will find friction everywhere that objects come into contact with each other. Here are some examples: Two hands rubbing together,your ski rubbing on the snow,hammer hitting a nail,gases,like fraction with the air slowing down your car,or liquids and water slowing down a boat.

Examples of friction in everyday life: - Driving the car to school - Rubbing your feet on the carpet - Walking - Writing
6 types of friction
Static friction- When a body is forced to move along a surface but movement does not start. - Pushing a shopping trolley - Moving a sofa
Kinetic friction- When a body just starts moving along a surface. When external applied force is sufficient to move a body along a surface then the force which opposes this motion is called as kinetic frictional force. - A car’s windshield and the air as you drive into the wind. - Moving heavy furniture
Rolling friction- Is the force resisting the motion when a body rolls on a surface. - A ball - Tyre - wheel
Fluid friction- Fluid friction is the resistance to an object's motion through a liquid or gas. - A car - Window
Skin friction- A component of drag, the force resisting the motion of a fluid across the surface of a body.
Internal friction- The force resisting motion between the elements making up a solid material while it undergoes deformation.
Abrasion- Abrasion is the system of breaking away or rubbing away by the means of friction and erosion.
Erosion- Erosion is the process of wind and water breaking down soil or solid rock.
