Greased machine parts produce less friction because the lubricant reduces the resistance between moving surfaces, allowing them to slide or rotate more easily. This helps decrease wear and heat generation, leading to smoother operation and potentially longer part life.
than what?
Fingerprints on glass can increase friction due to the oil and residue left behind, which creates a rougher surface than clean glass. This rougher surface allows for more interaction between the fingerprint and the object making contact, resulting in increased friction.
A rough, bumpy surface typically produces more friction compared to a smooth surface. The irregularities on the rough surface create more contact points between surfaces, leading to increased resistance and friction during movement.
Rubber will have a high coefficient of friction on most surfaces, but we cannot know whether there is more or less friction unless we have something to compare it to.
Carpet has more friction than tile. Tile has more friction than ice.
In general it means that there will be less surface friction on the material. On vehicles this can be done by reducing the impact area at the front and by integrating smooth curves for the air to follow. Surface polishing can also increase airflow and reduce friction.
Less heat
You want less friction. Then you will go faster.
Using a rubber mat in the shower typically produces more friction compared to a smooth surface. The texture of the rubber mat creates a better grip for your feet, which can help prevent slips and falls in wet conditions.
