How does friction occur when two surfaces come in contact with each other?
Wiki User
∙ 13y ago
Friction occurs when microscopic asperities on two surfaces interlock, preventing smooth sliding motion. This resistance to motion results in the generation of heat and the force required to overcome it is proportional to the force pushing the surfaces together.

Does friction only occur on earth?
Friction occurs between two surfaces in contact with each other. While friction is commonly experienced on Earth due to the presence of solid surfaces, it can also occur in other environments, such as in space where interactions between objects can create friction.
Can Friction occur in a vacuum?
No, friction cannot occur in a vacuum because friction is caused by the interaction between two surfaces when they are in contact. In a vacuum, there is no air or any other medium present for surfaces to interact with, so there is no friction.
Why does friction occur on an objects surface?
Friction occurs on an object's surface due to the interaction between the roughness of the surfaces in contact. As the surfaces move against each other, the irregularities in the surfaces interlock and create resistance to motion. This resistance results in the force of friction, which opposes the relative motion between the surfaces.
What acts only between surfaces that are in contact?
Friction is a force that acts between surfaces in contact with each other, resisting their relative motion.
Does friction act at a distance?
No, friction is a force that acts between two surfaces that are in contact with each other. It is a result of microscopic interactions at the surfaces of the objects in contact.

How does friction occur?
When surfaces opposing movement on each other.

When does friction occur or happen?
Friction occurs when two surfaces come into contact and slide or rub against each other, creating resistance to motion. It is a force that opposes the relative motion or tendency of motion between the two surfaces.
When is there friction with no movement?
Friction can occur without movement when there is static friction, which happens when two surfaces are in contact but not moving relative to each other. Static friction prevents movement from occurring until a certain force threshold is exceeded.
What prevents surfaces in contact from sliding past each other?
The frictional forces between the surfaces prevent them from sliding past each other. These forces arise due to the roughness and interlocking of surface asperities, which resist relative motion. Additionally, the normal force acting perpendicular to the surfaces helps maintain contact and resistance to sliding.
The friction between moving surfaces is called?
The friction between moving surfaces is called kinetic friction. It occurs when two surfaces are in contact and move relative to each other, causing resistance to their motion.
When solid surfaces slide over each other what is the kind of friction?
When solid surfaces slide over each other, the friction is known as sliding friction. This type of friction occurs when two solid surfaces are in contact and slide against each other, resulting in resistance to the motion.
Why does coating surfaces with oil reduce friction?
Coating surfaces with oil reduces friction by creating a lubricating layer between the two surfaces in contact, which helps to reduce direct metal-to-metal contact and friction. This lubricating layer allows surfaces to slide past each other more easily, resulting in lower friction and wear on the surfaces.
