Sir Issac Newton developed the laws of motion. Here's a basic summary of his three laws:
1st law (law of inertia): An object at rest stays at rest and an object in motion tends to stay in motion unless acted upon by an unbalanced force.
2nd law (law of acceleration): An net force applied to an object produces an acceleration (F= ma).
3rd law (law of interaction): For every action, there's an equal and opposite reaction.
Static friction: the force that resists the initial movement of an object at rest. Kinetic friction: the force that opposes the motion of an object already in motion. The coefficient of friction: a constant that measures the friction between two surfaces.
The laws of dynamic friction describe the relationship between the force required to overcome friction between two surfaces in motion and the normal force acting perpendicular to those surfaces. These laws state that the force of friction is proportional to the normal force and is independent of the surface area in contact, while the coefficient of friction relates the force of friction to the normal force.
The laws of friction state that frictional force is directly proportional to the normal force and independent of the contact area. The force required to overcome static friction is greater than the force required to overcome kinetic friction. Friction acts in the opposite direction of the motion or intended motion of an object. In sports, these laws affect player movements such as running, stopping, and changing direction. Athletes must consider these laws to optimize their performance, for example, by maximizing grip in activities like sprinting or cutting.
Friction is a force that resists relative motion between two surfaces, leading to energy loss in the form of heat. The laws of conservation of energy state that energy cannot be created or destroyed, only transferred or transformed from one form to another. Friction causes energy to be dissipated, leading to a loss of mechanical energy in a system.
John Walker, an English chemist, is credited with inventing the first friction matches in 1826. They were made by coating wooden splints with a mixture of potassium chlorate, sulfur, sugar, and gum.
Newton discovered friction along with most other forces like gravity. he also invented the 3 laws of motion and if he didn't know about friction he couldn't have invented the laws. Agent Wolf
Sate laws of friction
Friction was not invented just discovered
Friction wasn't invented, it is an interaction between objects : "Friction is the force resisting the relative lateral motion of two solid surfaces in contact, or a solid surface in contact with a fluid"

Friction can slow down the rock
Force applied parallel to ground = force of fricton.

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.
