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.

Force is the external agent that produces motion. Basically, there are two main types of forces, contact forces, and non-contact forces. Gravitational forces, electric forces, magnetic forces, nuclear forces, frictional forces are some examples of force.

Types of Forces

• Different types of forces and their examples. Force can be classified into two broad categories. Contact forces.
• I. Frictional force. As an object moves across a surface it causes friction.
• II. Tension force.
• III. Normal force.
• IV. Air Resistance force.
• V. Applied force.
• VI. Spring force.
• I. Gravitational force.

Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other. Dry friction is subdivided into static friction (“stiction”) between non-moving surfaces, and kinetic friction between moving surfaces.

Friction is the force that opposes motion between any surfaces that are in contact. There are four types of friction: static, sliding, rolling, and fluid friction. Static, sliding, and rolling friction occur between solid surfaces. Fluid friction occurs in liquids and gases.

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.

Friction manifests as heat energy generally and sometimes as noise. When objects are moving against each other, there is a generation of kinetic energy. The biggest disadvantage of friction is wear and tear that happens as a result of friction. …

Rolling friction

Driving of the vehicle on a surface- While driving a vehicle, the engine generates a force on the driving wheels. This force initiates the vehicle to move forwards. Friction is the force that opposes the tyre rubber from sliding on the road surface. This friction avoids skidding of vehicles.

There are different types of friction. A book moving across the desk is an example of sliding friction. Air resistance is a type of fluid friction. As an object falls, air resistance pushes up on the object. When you ride a bicycle, the contact between the wheel and the road is an example of rolling friction.

10 examples of friction in our daily life

• Driving of a a vehicle on a surface.
• Applying brakes to stop a moving vehicle.
• Skating.
• Walking on the road.
• Writing on notebook/ blackboard.
• Flying of aeroplanes.
• Drilling a nail into wall.
• Sliding on a garden slide.

First law of friction: The amount of friction is proportional to the normal force exerted between the surfaces. Second law of friction: Friction does not depend on the area of contact between the object and the surface. Third law of friction: Friction force also depends on the nature of the surfaces in contact.

In any type of vehicle—such as a car, boat or airplane—excess friction means that extra fuel must be used to power the vehicle. In other words, fuel or energy is being wasted because of the friction. Fluid friction or air resistance can greatly reduce the gas mileage in an automobile.

Answer. Friction is the resistive force which prevents the motion of two solid surfaces,liquid layers or any kind of material elements sliding against each other. That’s why it is more useful than the wheel and the hub friction.

Following are the examples of helpful friction: i) Walking on the road is because of the helpful friction between the foot and the road. ii) Writing using pen or pencil is another example of helpful friction.
