Friction can decrease when a lubricant is introduced between two surfaces, creating a slippery barrier that reduces the resistance between them. Another factor that can reduce friction is polishing or smoothing the surfaces to make them slide more easily over each other. Additionally, reducing the force pushing the surfaces together can also decrease friction.

What causes speed to decrease?
Speed can decrease due to forces like friction, air resistance, or gravity acting in the opposite direction to the motion. Additionally, factors like an increase in mass or a change in the surface conditions can also cause speed to decrease.
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.
When does friction decrease?
Friction will decrease if the coefficient of friction decreases. This can be caused by having a smother surface up to a point. (When two surface are TOO smooth the friction actually increases due to molecular attraction.)
Is it true or false that friction reduces the efficincy of a machine?
True. Friction causes resistance within a machine, leading to loss of energy in the form of heat. This decrease in efficiency can result in the machine requiring more energy input to overcome friction and perform its intended task.
What force causes a bike to slow down when you stop pedalling?
Friction causes the bike to slow down.
What causes a decrease in the hose pressure in swimming pool cleaners?
Friction
What causes speed to increase or decrease?
Presence of friction, incline and so on.
What causes skateboard speed to increase or decrease?
Gravity, friction, or wind drag.
Do ball bearings increase or decrease friction?
Decrease friction .
How do skaters decrease sliding friction?
by using a lubricant to decrease the friction.
How could you decrease the friction?
Friction is decreased by means of lubrication.
How do you decrease the amount of force needed to do work?
Decrease friction.
Does friction decrease or increase?
Wax, due to it filling the pores that cause friction will reduce friction.
How can you decrease magnitude of friction?
you don't.
