Friction Flashcards
The rougher are the surfaces
More is the friction
While stating the laws of friction which friction should you specifically keep in mind ?
Limiting
Which plane is formed by the wheels or the rollers
Inclined
In rolling friction, friction is equivalent to ?
Inclined plane
In rolling friction, friction is equivalent to ?
Inclined plane
Smaller the depression
Smaller the rolling friction
Commenest liquid and gas
Water and air
Small surface area in air
Experiences less friction
Small surface area in air
Experiences less friction
Explain friction in meteor
Meteor enter at a high speed and consequently experience the same friction by the air , due to high friction the temperature of meteor rises to such a high degree that they catch fire
Explain friction in meteor

Spaceships are provided with
Hat shield
When we walk , where does the friction comes from?
Forward direction by the ground
Disadvantages of friction
Wear n tear , increases energy, reduces the speed
Soap solution in decreasing the friction
It’s used in reducing friction in high speed cutting and grinding machines and the heat produced by it is taken away by the water present in it
