If a fluid in laminar flow flows around an obstacle, it exerts a viscous drag on the obstacle.
Frictional forces accelerate the fluid backward (against the direction of flow) and the obstacle forward (in the direction of flow).
The viscous drag force increases linearly with the speed of the fluid.

What is an example of viscous Friction?
oil in a car's engine reduces viscous friction and wear
Why oil and grease and not water is used in machines as lubricant?
No, water is not lubricant. for example:- if water is spread on ground then we slip then people thinks that water is lubricant but is not the case so the floor is smooth the water is not lubricant. oil and grease are lubricant and they are used in machines.
How can you lessen friction?
You can use a lubricant. The object slides along the lubricant. Like slipping on grease or oil
What is an oil lubricant?
Lubricating oil, sometimes simply called lubricant/lube, is a class of oils used to reduce the friction, heat, and wear between mechanical components that are in contact with each other. ... Mineral lubricating oils are currently the most commonly used type because of the low cost of extracting the oils from crude oil.
How is friction reduced in the typewriter?
Lubricant. Usually with a light machine oil.
Can viscous oil freeze?
Freezing oil will be extremely viscous. Oil does not freeze easily. The freezing point of oil is very low like -30oC.
Used to reduse friction?

What is full synthetic and semi synthetic oil?
Oil usually refers to petroleum lubricant. It is refined product of crude oil pumped from underground oil fields around the world. Synthetic oil is lubricant manufactured as a substitute for petroleum lubricant, it was first developed by Germany during WWII to make up their shortages in oil. Semi synthetic oil is a mixture of petroleum lubricant and syntetic lubricant.
What do you call thick oil?
viscous
What is an example of viscous Friction?

What is the definition of viscosity?
Viscosity is a fluid's resistance to flow. Fluids becomes less viscous as the liquid's temperature increases, becoming more viscous as the fluid gets cooler. A viscous fluid is sticky, thick and syrupy to a greater or lesser extent. Examples Treacle is quite viscous, but water is not. Hot engine oil is less viscous ('thinner') and runs more quickly and smoothly than cold engine oil.
Is oil a lubricant?
Yes.
What is the definition of lubricate?
To make smooth or slippery; as, mucilaginous and saponaceous remedies lubricate the parts to which they are applied., To apply a lubricant to, as oil or tallow.
Discuss how effective a car suspension damper would be if the oil in the damper was replaced by oil that was much more viscous?
The effectiveness of a car suspension damper after exchanging the oil in the damper with oil that is much more viscous is increased. The viscous oil gives a smoother and a more powerful effect to the suspension damper.
What is the purpose of checking acid value of lubricant oil?
The purpose of checking the acid value of the lubricant oil is that it determines the efficiency.
Is Ostwalds viscometer used to measure viscosity of more viscous oil?
Yes, the Ostwalds viscometer can be used to measure the viscosity of more viscous oil.
What is the synonym of grease?
lubricant or oil
