I cant remember but I hope this answers, you have to use brakes in a car to stop the car therefore friction is increased (or it stops).

friction is a force which opposes the direction of the movement of a certain body. reducing the friction between moving parts will lead to an increase of acceleration or speed of that particularly body.
Friction can be unhelpful in situations where you want to minimize energy loss, such as in machinery where friction causes wear and tear on moving parts, reducing efficiency. Additionally, in sports like speed skating or car racing, reducing friction can help increase speed and performance.
No.
Grease is important because it provides lubrication between moving parts, reducing friction and wear. It helps to absorb shock and reduce heat generated during operation, therefore extending the lifespan of components in machinery and equipment. Grease also helps to seal out contaminants and prevent corrosion, keeping equipment functioning properly.
Lubricant is important for machinery and equipment because it reduces friction between moving parts, which helps prevent wear and tear, overheating, and damage. This helps to extend the lifespan of the machinery and equipment, improve efficiency, and reduce the need for costly repairs and maintenance.
WD50 lubricant offers several benefits for machinery maintenance, including reducing friction and wear on moving parts, extending the lifespan of equipment, improving overall performance and efficiency, and providing protection against rust and corrosion.
The reduction of friction in the moving parts of machinery is the primary usage of oil.
Friction is the force that primarily causes wear and tear of machinery. As moving parts rub against each other, friction generates heat and abrasion, leading to material loss and degradation over time. Regular maintenance and lubrication can help reduce the impact of friction on machinery.
A lubricantis a substance introduced to reduce friction between moving surfaces. It may also have the function of transporting foreign particles. The property of reducing friction is known as Lubricity. (Slipperiness) This causes less friction.
Graphite is better than oil for lubricating hot machinery because it can withstand higher temperatures without losing its lubricating properties. Oil tends to break down and evaporate at high temperatures, reducing its effectiveness as a lubricant. Graphite also has lower friction coefficients, making it more effective in reducing wear and improving the efficiency of moving parts in hot machinery.
Friction creates heat. Heat could melt machine parts if it becomes too high. That's why many machines use lubricants while they're drilling or shaping metal.
