Leonardo Da Vinci dont know when though
There are three main ways of electrically charging an object:By frictionBy contactBy induction
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
Lubricants reduce friction by replacing sliding friction with fluid friction.
Friction is reduced on a wet floor.
he discovered it someday in his life was this helpful i sure hope so
Leonardo didn't discover it... Fibonacci did.

Arthur-Jules Morin (1795-1880) coined the term "coefficient of friction" and was the first to demonstrate it's applications. Perhaps the first person to experiment with sliding friction was Leonardo da Vinci (1452 - 1519) . He discovered the Bilfinger Value and originated Amontons' Laws of friction. They were later rediscovered by Guillaume Amontons in 1699. Morin was able to discover the coefficient of friction thanks to Isaac Newton's Laws of motion.

Several famous scientists and engineers contributed to our understanding of friction. They include Leonardo da Vinci, Guillaume Amontons, John Theophilus Desaguliers, Leonard Euler, and Charles-Augustin de Coulomb. Their findings are codified into these laws, 1. The force of friction is directly proportional to the applied load. (Amontons 1st Law) 2. The force of friction is independent of the apparent area of contact. (Amontons 2nd Law) 3. Kinetic friction is independent of the sliding velocity. (Coulomb's Law)
All the human organs were known before Leonardo's time. The novelty was that he made sketches of them.
