The friction experienced by a body when in motion?
The friction experienced by a body when in motion is called kinetic friction. This type of friction occurs between two surfaces that are in contact and moving relative to each other. The amount of kinetic friction depends on the materials of the surfaces and the force pressing them together.
Why friction donot effect your body?
Friction does affect the human body, for example when rubbing against rough surfaces can cause skin irritation or blisters. However, the body has adapted mechanisms, such as calluses and skin thickness, to minimize the effects of friction. Additionally, the body produces lubricants like sweat to help reduce friction between surfaces, such as between skin and clothing.
How the coefficient of friction between a body and a surface change if the mass of the body is doubled?
The coefficient of friction between a body and a surface does not change if the mass of the body is doubled. The coefficient of friction is a property of the material of the surfaces in contact and their interaction, not the mass of the body.
What is the angle of friction?
The angle of friction is the angle at which a body will start sliding on a surface. It is equal to the arctangent of the coefficient of static friction between the two surfaces in contact.
When a body slides or rolls over the other body the force of friction is said to be?
When a body slides or rolls over another body, the force of friction is called kinetic friction. This friction arises due to the contact between the surfaces of the two bodies and opposes the relative motion between them.
What surfaces of the body have papillary ridges?
Papillary ridges are found on the fingertips, palms, and soles of the feet. These ridges form unique patterns that can be used for identification purposes, such as with fingerprinting.

Does friction use static?
Yes, friction can involve static friction when two surfaces are not moving relative to each other, and kinetic friction when the surfaces are in motion. Both types of friction occur due to the interaction between the surfaces at a microscopic level.

What 2 factors determine the strength of the friction between 2 surfaces?
On a flat surface it would be the friction coefficient and the weigh of body.
When a body just start to move which friction take place?
When a body just starts to move, the friction that is present is static friction. This friction occurs between surfaces that are in contact but not moving relative to each other, resisting the initiation of motion. Once the body overcomes this static friction, it transitions to kinetic friction as it continues to move.
What is limiting value of friction?
The maximum friction that can be generated between two static surfaces in contact with each other. Once a force applied to the two surfaces exceeds the limiting friction, motion will occur. For two dry surfaces, the limiting friction is a product of the normal reaction force and the coefficient of limiting friction.
Why friction does not occur in smooth surfaces?
It is wrong to say that friction doesn't occur in smooth surface.. As ideally, no such surface exists, which has 0 value of friction. We can say that the magnitude of friction force is less in smooth surfaces as compared to that in rough surfaces. Friction opposes the motion of a body. When we go to the molecular level, we can see that the surface of a plane is not smooth but rough.. We cannot see that roughness through naked eyes. But the amount of roughness differs from object to object. The so called smooth surfaces have less roughness as compared to un-smooth surfaces. Hence, the magnitude of friction is LESS in smooth surfaces...
Example of ways increasing friction?
Increasing friction can be achieved by using materials with rougher surfaces, increasing the weight pressing the surfaces together, or increasing the normal force acting between the surfaces. Additionally, applying more force parallel to the surfaces in contact can also increase friction by creating more interlocking between the surfaces.
