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.
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.
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.
How does a car accelerate speed?
A car accelerates when the engine produces more power than what is needed to overcome friction. The car reaches its maximum speed (on the level) when all the engine power is being used to overcome friction.
What is the purpose of an engine block in the context of a car?
An engine block is used in cars to support the components of an engine. It is also used to transfer heat from friction to the atmosphere and engine coolant.
How is friction between the moving parts of a car engine reduced?
Friction between the parts of an engine is reduced by applying oil between its parts. mobiloil is particularly used for this purpose.
What is an example of force acting on a moving car?
Somebody pushing the car; friction slowing down the car; gravity acting on the car (this is especially relevant if the car is going up or down a slope); the engine pushing the car forwards.
How is friction useful when driving a car?
well friction is almost the essential component in a car. You have friction everywhere. You have friction in your engine, your brakes, your transmission, and on your tires. Friction helps you move and stop. Most cars today waste the energy made from friction but some hybrids use all of these frictions to charge their battery to start the car over and over again, or help it down the road.
Why does the momentum of a car will not continue if you turn the car off?
The main reason a car will slow down when the engine is turned off is due to friction, there is friction on all moving parts which converts the kinetic energy of the cars movement into heat energy.
How does friction change how far a car goes?
Friction does work to slow down the car. Thus, the more friction there is, the less distance a car can go.
How does friction affect the balloon powered car?
Friction will slow it down
What is one way friction affects a car?
Creates heat in the engine (friction of moving parts creates heat) Reduces efficiency (friction in the drivetrain, as well as air resistance, slows the car down) Causes the tires to wear out (friction between the road and the rubber causes the rubber to wear)
