Friction in a car engine is reduced by using proper lubrication, such as engine oil, to create a smooth surface between moving parts. Additionally, improving the design and materials of engine components can help minimize friction. Regular maintenance and keeping the engine's parts clean can also help reduce friction.

What is friction and how does it affect the motion of an object?
Friction is when an object resists to move over another object. For example, when you rub two styrofoam cups together, you hear a squeaky noise. You are creating friction between the two cups, thus producing a squeaky noise. Friction tends to slow down objects in motion, such as when you throw a brick through the air, it will not go far, depending on the force you used to throw the brick. Its speed will gradually decline due to the brick's friction with air. Now if you threw a football through the air using the same force that you used to throw the brick, it will go a lot farther than the brick because of its shape. The curved edge of the football makes it easier to 'slice' through the air, thus creating less friction. It is the same aspect with the shape of a car. The front of the car is blunt, so it will 'cut' through the air without much friction.
How and why friction is cut down on a dance floor?
Friction on a dance floor is reduced by using materials that are smooth and non-sticky, such as hardwood or vinyl. This helps dancers move more freely and smoothly across the floor without resistance. Additionally, applying a thin layer of wax or powder can further reduce friction and allow for seamless movements during dancing.
What is the principle of friction sawing?
Friction sawing is a metal cutting process where the heat generated by friction softens the material being cut, which is then removed by a sharp-edged tool. This method allows for high cutting speeds and the ability to cut through hard and tough materials efficiently. The principle relies on the heat generated during the process to facilitate the cutting action.
Explain how air friction is reduced in cars and bicycle?
The front of the car is blunt, making it easier to 'cut' through air, thus reducing friction. For a bicycle, since it is very thin and angular, its shape (and the tires') makes it easier for air to glide over the bicycle, thus reducing friction.
What role does friction play in cutting wood?
Friction helps to transfer the force from the cutting tool to the wood, allowing the tool to remove material. It also generates heat, which can help soften the wood fibers, making it easier to cut. However, too much friction can cause the cutting tool to overheat and wear out prematurely.
What is used to cut down friction in a car engine?
How- cooling oil why- overheating is bad for the engine parts
How and why friction is cut down in a car engine?
How - with cooling oil Why - because friction causes heat, and overheating is bad for moving parts.
What is friction between moving parts of an engine?
Friction is cut down in a car engine for two very important reasons. First, cutting down friction increases horsepower. It takes horsepower to overcome friction; so anything that can be done to cut down friction will increase the horsepower. Second, friction causes heat to be produced. Too much heat is bad, because if the engine gets too hot, then metal is softened and weakened, leading to failure of engine parts. The engine has a cooling system to remove unwanted heat, but too much friction would require a larger and more efficient cooling system to remove the excess heat, which would add expense and weight to the car. Motor oil is used to cut down the friction in the car engine. Also, very close tolerances in production of engine parts helps to cut down friction.
Why is friction an important factor to consider when designing a race car?
Gravity is good. It keeps the cars down on the track, and the fans in their seats. Friction is bad. If there was no friction, then you could cut your engine when you hit 200 and just keep going. But friction robs your kinetic energy, so if you back off your engine, then your car slows down.
Why is friction cut down in a hovercraft?
How is friction cut down in a hovercraft? This is done by hovering over the surface Why is friction cut down in a hovercraft? Because the surface of the hovercraft is smooth
Where do racing car drivers not want friction and why?
Down the straights because it can slow their top dpeed down and they need to cut through the air as cleanly as possible.
How and why is friction cut down in a hovercraft?
Friction is cut down in a hovercraft by the large volume of air that blows out from under the skirt, making the skirt rise above the ground. In essence, the hovercraft is floating on a bubble of air, and has very little friction with respect to the ground.
What are the Small balls that help cut down on friction inside machines?
Ball bearings
Why is friction cut down on a dance floor?
Friction on a dancefloor is reduced by the highly polished floor and leather bottomed shoes worn by the dancers
How does an engine turn off?
Gasoline engine - spark is cut off when ignition is turned off Diesel engine- fuel is cut off when engine is shut down
Why is your car cooling fan still run after you stop the engine or cut it off?
It's probably an electric fan that reacts and works if the engine reaches a certain temperature. Sometimes that means keeping going for a while even after you shut down the car.
Why would your car engine cut off while driving downhill?
why does it matter if you're driving down a hill? At least it didn't cut off when you were driving up a hill? And I don't know why it would cut off I'm 13.
