Moving mechanical parts usually need some degree of lubrication so that they do not waste energy in overcoming friction. A very simple case of this would be a door hinge. If the door hinge has too much friction, the door squeaks when you open or close it. It moves smoothly and quietly if it is lubricated. With something like the motor of a car or an airplane, friction would present much more serious problems than the squeak of a door hinge. You would get terrible overheating and eventually an explosion, in an unlubricated motor.
What else can I help you with?
How do cyclists reduce friction in the velodrome?
Professional bike riders want to reduce friction, because friction is a force of two objects rubbing up against each other, therefore slowing you down.
What force would help you slide down a slide?
Gravity? the strength of the floor?
Is there a force that can go against friction?
No. Friction can only slow an object down. If friction were imparting a force greater than that of the applied forces, then friction in and of itself would actually be causing the object to move, which does not happen.
The amount of friction depends on what?
Friction depends on the surface that the object is going against. If an applied force is used to push a box on a ground, the friction is the surface of the ground, may the ground be rough or smooth, there is a force that goes against the applied force. Air friction is also a type of friction that many physics question does not account for, because it is a virtually small force.
Is Friction reduced between polished surfaces?
when we polish surfaces, the molecules or atoms of surface come closer to each other so there is no space for fiction so it is reduced but not reduced to zerowe cant reduce friction to zeroWhen we polish a rough surface smoothly,the unequalities gets reduced,therefore friction is reduced
What is the relationship between friction and unbalanced force?
Friction is a force that opposes motion between two surfaces in contact. When there is an unbalanced force acting on an object, it can overcome the force of friction and cause the object to accelerate. In situations where the unbalanced force is less than the force of friction, the object will remain at rest.
Is friction a invisible force?
Friction is not an invisible force. It is the force that opposes the relative motion or tendency of such motion of two surfaces in contact. Its effects can be observed and measured in various situations.
Does it take the same amount of force to start something as it does to keep it moving?
No. It takes a force to put something in motion, and it takes force to stop it. To keep it moving requires zero force. If there is no opposing friction force, it will continue moving forever. If you can significantly reduce the friction, a small force can keep an object moving - just enough to counteract the force of friction.No. It takes a force to put something in motion, and it takes force to stop it.

When maglev train is lifted which force reduce?
Friction. Oonce the train is clear of the track, there is no friction to slow it down.
What force do skin tight ski pants reduce?
air drag
How to reduce frictional force?
To reduce frictional force, you can use lubricants such as oil or grease to create a slippery layer between surfaces. You can also use smoother materials or surfaces, or apply a force perpendicular to the surfaces to reduce the contact force. Lastly, minimizing surface roughness and keeping surfaces clean can also help reduce friction.
Rolling friction always reduce the net force acting against an object's motion to zero?
Rolling friction does not reduce the net force acting against an object's motion to zero. Rolling friction is a resistive force that opposes the motion of an object moving along a surface, but it does not completely eliminate the net force. The net force is the vector sum of all forces acting on the object, including rolling friction.
How can you decrease the magnitude of friction?
To decrease the magnitude of friction, you can apply a lubricant between the surfaces in contact, use smoother materials to reduce surface roughness, or apply a force to counteract the friction force. Reducing the normal force between the surfaces can also decrease friction.
Should one add static friction and kinetic friction together to find the total friction force?
No, static friction and kinetic friction are separate forces that act in different situations. When an object is at rest, static friction opposes the applied force. When the object is in motion, kinetic friction opposes the motion. To find the total friction force, you would just consider the friction force relevant to the situation.
How can you reduce and increase friction?
To reduce friction, you can use lubricants to create a smooth surface between objects in contact. To increase friction, you can increase the force pushing the objects together or use materials with rough surfaces that grip each other more firmly.
How do cyclists reduce friction in the velodrome?
Professional bike riders want to reduce friction, because friction is a force of two objects rubbing up against each other, therefore slowing you down.
How does a ball reduce friction?
A ball can reduce friction by converting sliding friction into rolling friction. When a ball rolls on a surface, the point of contact continuously changes, reducing the overall friction experienced. Additionally, the round shape of a ball helps to distribute the force more evenly, further reducing friction.
