Friction is the force that opposes the relative motion of two surfaces in contact. To decrease friction, you can use lubricants like oil or grease between the surfaces, use smoother surfaces, reduce the force pressing the surfaces together, or introduce rolling motion instead of sliding motion.
What else can I help you with?
When is decreased friction helpful?
Decreased friction is very helpful in working machinery, because friction causes wear and tear.Mainly its very helpful in moving parts. Decreased friction is also helpful in electric cables and wires, as reduced friction reduces energy loss via heat.
How can the friction between two objects be decreased?
The friction between two objects can be decreased by using lubricants such as oil or grease, which create a slippery layer between the surfaces. Alternatively, polishing or smoothing the surfaces can reduce friction by removing rough areas that create friction. Using ball bearings or rollers can also reduce friction by allowing smooth movement between the objects.
What True or false lubricants reduce friction by replacing sliding friction with fluid friction?
True. Lubricants reduce friction by forming a thin layer between moving surfaces, which helps to replace sliding friction with fluid friction. This allows for smoother movement and decreased wear on the surfaces in contact.
Is friction increased by lubrication?
No, friction is actually decreased by lubrication. Lubrication helps to reduce the resistance between surfaces in contact, allowing them to slide past each other more easily, thereby reducing friction.
What is spring friction?
Spring friction refers to the resistance encountered when compressing or extending a spring due to internal friction between the coils. The friction generates heat, resulting in energy loss and reduced efficiency of the spring. It can lead to decreased performance and premature wear of the spring over time.
How could you decrease the friction?
Friction is decreased by means of lubrication.

What is an object that stops working well due to friction?
A car engine can stop working well due to friction if the components, such as pistons and cylinders, experience excessive wear and tear. This friction can cause decreased performance and eventually lead to engine failure.
How does heat friction affect the performance of materials in high-speed applications?
Heat friction in high-speed applications can cause materials to degrade and lose their strength, leading to decreased performance and potential failure.
Examples where friction is a problem on the earth?
Friction is a problem when walking on icy surfaces, as it can cause slips and falls. Friction can also be an issue when trying to push or pull heavy objects, as the force needed to overcome friction can be significant. Brakes in vehicles rely on friction to slow down or stop, so issues with friction can lead to decreased braking performance.
What are disadvantages for rolling friction?
Rolling friction can create heat and wear on the surfaces in contact, leading to energy loss and decreased efficiency. It can also vary with different surfaces and conditions, making it difficult to predict accurately.
How is friction increased and decreased?
It is when the surface areas in contact increase or decrease. With increased surface areas in contact, friction increases.The faster an object moves against another object, the greater the friction will increase. Same basic principle can be applied for the decrease in friction, by slowing down movement. For example, humans stay grounded tongue ground do to the force of gravity, in which the earth is spinning very fast but you can't feel it, the force of the earth spinning (friction) causes gravity to hold us to the ground.Friction, as a physical term, is the force that opposes to movement when two objects contact each other in the shpere of cinematics. It is produced by the contact between atoms. Friction as a physical property cannot be decreased nor increased. But, by placing other object between these initial two can give different friction between those two, reducing the force that opposes to movement and therefore, at the end of the ecuation, reducing friction.Increase friction by having rougher surfaces rubbing together. Decrease friction by having smoother surfaces rubbing together. Remove oil or grease to increase friction. Add oil or grease to reduce friction.Classical friction depends on two factors: weight and friction coefficient. When decreasing weight is usually problematic or impossible, friction can be decreased by lowering the friction coefficient. For this purpose different kinds of surfactants and oils are used or even air.to decrease friction you need to use lubricants,while to increase friction you need to use breaksyou incraese friction when something is sticke and hard to slide on each other.____________________________________________By decreasing area of friction and using oils of friction surface.
What an example of a machine in which friction is both an advantage and a disadvantage?
A car is an example of a machine where friction can be both an advantage and a disadvantage. Friction between the tires and the road allows the car to accelerate, brake, and turn smoothly, providing traction. However, friction also causes wear and tear on the tires and causes the engine to work harder, leading to decreased fuel efficiency.
