1. What is Friction Force?
The frictional force which opposes motion that friction result from two surfaces routing against each other on moving relative to one another as the force of frictional reaches the motion of an object to retards the motion for always act in a direction opposite to that of the motion of the body fictional force can hinder the motion of an object by slowly down or prevent an object from moving at on this fictional can be Kinetic or static.
2. What are the types of Friction Force?

1. Fluid Friction
= Fluid friction is the force of friction exerted by fluids liquid and gases on object moving through them.
2. Reducing friction
= The material used to make a surface smooth call lubricant the most commonly used lubricants are oils, graphite, boric .powder etc.
3. Sliding friction
= The resistance offered when one surface rights over the other surface.
4. Rolling friction
= The resistance to its motion when one body rolls over the other.

1. Friction help us to walk and run what will happen if you step on a banana peel you will sleep the pill makes the surface more friction between your feet and degrees signal between one and the ground or want to work for processing of the ground without slipping and falling down on slippery surfaces such as I saw banana shoes slip and slide instead of grief and because of the lack of station make working fiction announce car tires to grave and roll along the road without skidding.
2. Vehicle breaks make use of friction what do you do when you want to stop a running bicycle you apply brakes a break in the friction between the tires and the road and the bicycle stop if an object moves on a frictional less surface it will never stop you cannot move or stop or change the direction of a moving car in the absence of friction.
3. Friction can produce heat a match stick light up when rubb against the side of a Matchbox due to heating effect of friction rub your hands together and soon afterwards Cup your face you feel that heat it is produced from no hair put the friction between your hands.

1. Friction radio the speed of a moving object you cannot move faster on rough road on your bicycle it is difficult to drag a heavy object due to friction that oppoes the motion.
2. Friction causes wear and tear rubber tires of ab wear and tear due to friction produces between the tire and the role while running the sole of shoes get worn out due to friction cause between the source and the ground while walking.
3. Friction between the moving parts of an engine receives the engines motion and turns to energy into heat reducing the engine efficiency frictional it is not come when it damage the machine parts such as car brakes.
4. A large amount of fuel is wasted while running machines to overcome friction.
Summary,
1. Friction is a contact force.
2. Friction results from two surfaces robbery against each other or moving with respect to one another.
3. Friction always and in the direction opposite to that of motion it can enter the motion of an object or prevent an object moveing at all.
4. The magnitude of force of friction depends on the nature of the surface is contact and the weight of the sliding body.
5. Sliding friction offer when an object lines and rolling friction offered when an object start rolls on other surface.
6. Rolling friction is less than sliding friction show a heavy shooting case can be post easily on wheels.
7. Friction causes near and dear it can produce heat it also reduces the speed of a moving body.
8. Friction helps to walk without slipping down right on paper and prevent a car from skidding.
9. We can reduce friction by oily and lubricating and using ball bearing in moving parts.
10. Streamline Shape of a body helps it to overcome fraction of adventure moving in a fluid.
11. The tyres of a car are treated to increase friction.
Answer:
There are two main types of friction, static friction and kinetic friction. Static friction operates between two surfaces that aren't moving relative to each other, while kinetic friction acts between objects in motion.
