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.
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.
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.
The surfaces used as the measure of lowest friction are generally wet ice on wet ice. Some materials, such as superfluid Helium III have no measurable friction.
Friction is the force that opposes motion when two surfaces come in contact. It affects the motion of an object by slowing it down or preventing it from moving. The amount of friction depends on the roughness of the surfaces and the force pressing them together.
Resistance keeps an object in place. This resistance can come from friction, which works against motion, or from an obstacle of some kind that is prohibiting movement. In terms of vertical motion, gravity holds all objects to the earth and keeps them firmly planted on the ground.An object at rest tends to stay at rest unless acted on by a forceAn object in place will stay in place unless acted upon by a force. So if you kick a box in place on the floor it will move. There is always a force of gravity pulling it down, bu the force of gravity is resisted by the floor which keeps it in place (equilibrium - no net force). If you cut around it and make a hole in the floor it will move straight down.
Friction on a dancefloor is reduced by the highly polished floor and leather bottomed shoes worn by the dancers
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
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.
How - with cooling oil Why - because friction causes heat, and overheating is bad for moving parts.
Ball bearings
How- cooling oil why- overheating is bad for the engine parts
Absolutely not, Although he does cut a dash on the dance-floor. and he is fond of a lesbian or two, he definitely does not walk the dirt track
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.
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.
There is a thick liquid produced in the joint spaces to cushion and reduce friction. This viscous fluid is called synovial fluid.
Down the straights because it can slow their top dpeed down and they need to cut through the air as cleanly as possible.
