What is the rubbing called when one surface moves against another surface?
Friction is the force resisting the relative motion of solid surfaces, fluid layers, and material elements sliding against each other.
What is the force that acts between moving surfaces?
Friction
Friction is a force that resists movement between two surfaces sliding against each other. When surfaces in contact move relative to each other, the friction between the two surfaces converts kinetic energy into heat.
Which force acts only when two surfaces move over each other?
Friction acts only when two surfaces move over each other.
What is the frictional resistance to motion?
Friction is the resistance to motion of one object moving relative to another. It is not a fundamental force, like gravity or electromagnetism. Instead, scientists believe it is the result of the electromagnetic attraction between charged particles in two touching surfaces.
What is the resistance of moving over another surface?
the resistance that one surface or object encounters when moving over another. Friction is the resistance that one surface or object encounters when moving over another.
Which is the best definition of the word resistance?
“A resistance emerged on a scale that the military had not anticipated.” The organized incitement of rebellion or civil disorder against authority or the state The resistance that one surface or object encounters when moving over another The capacity to endure the effects of a drug, poison, substance, etc.
What do you call a surface that repels water?
Scientists describe a surface that repels water as hydrophobic (HY-droh-FOH-bik). The term comes from the Greek words for water (hydro) and hating (phobic). The UCSD team describes the material it uses as super- hydrophobic. Their new energy system starts with table salt, or sodium chloride.
