How do oil and Vaseline reduce friction?
Oil and Vaseline reduce friction by creating a lubricating layer between surfaces, which helps them glide over each other smoothly. This reduces the contact area and prevents direct metal-to-metal contact, thereby minimizing friction and wear.
Why does lubrication increase friction?
Lubrication does not increase friction; it actually reduces friction between moving surfaces by creating a barrier that allows them to slide past each other more easily. The lubricant helps to smooth out any imperfections on the surfaces, reducing the resistance and wear that can occur from direct metal-to-metal contact.
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.
How is it that wood has more friction on metal than felt?
Wood has a rougher and less flexible surface compared to felt, leading to greater surface contact and thus more friction with the smooth surface of metal. Felt has a smoother and softer texture, which reduces the surface area in contact with metal and therefore decreases friction.
How does oil between Machines parts reduce friction?
The oil helps slick the two surfaces so that the molecular surfaces become easier to slide on with less friction. Julia Blander :P
Why is oil important in a car?
Because it lubricates. Instead of metal-on-metal contact, it puts a film of oil between the metal components, so that it's fluid friction, rather than friction between two solids - the latter of which causes excess wear and can actually fuse components together.
How do oil and Vaseline reduce friction?
Oil and Vaseline reduce friction by creating a lubricating layer between surfaces, which helps them glide over each other smoothly. This reduces the contact area and prevents direct metal-to-metal contact, thereby minimizing friction and wear.
How ball bearing reduce friction?
Bearings reduce friction by providing smooth metal balls or rollers, and a smooth inner and outer metal surface for the balls to roll against. The smoothness of the metal reduces the friction and the surface area.

This lubricating layer allows surfaces to slide past each other more easily, resulting in lower friction and wear on the surfaces.
How does oil reduce air friction?
Oil is mainly used to reduce friction between contacting surface, e.g., metal on metal - not to reduce air friction.

What are the similarities between soldering and welding?
In soldering and welding, 2 or more pieces of metal are joined by melting metal at the interface between them. When the molten metal cools and hardens, it physically bonds the pieces together.
Why does metal have so less friction?
Metal has low friction because its smooth surface allows for easier movement of objects over it. The atomic arrangement in metals allows for minimal resistance between surfaces, reducing friction. Additionally, metals can form a layer of oxide on their surface which further decreases friction between two metal surfaces.
You put oil in the engines of vehicles to cut down on frictionExplain why it is important to do this?
The oil leaves a thin film on a metal surface. This allows the moving parts to come in contact without producing friction which produces heat. It also reduces the amount of metal that is worn away between contact with two metal surfaces.
What is the difference between friction and antifriction bearing?
Friction bearings rely on direct contact between surfaces, such as metal on metal, to support loads, while antifriction bearings use rolling elements (balls, rollers) to reduce friction and support loads more efficiently. Antifriction bearings are typically smoother, have lower friction, and require less maintenance compared to friction bearings.
