One of the most important frictional forces to humans is the static frictional force that the ground exerts on a body. Without this force, walking would be impossible, cars would go nowhere.
An example of a non-frictional force is gravitational force. For example, when an object is in free fall, there is no friction acting on it.
An example of fluid friction is the air resistance felt by an airplane.
Rolling Friction, Static Friction, Sliding Friction, & fluid Friction
A example of friction is rubbing your hands together the heat you feel is friction. Oh dont be a shat head.
A piece of sand paper on a piece of wood is an prime example of rubbing friction.
Ice skating is because you dont go fast and there is rarely any friction
An example of unuseful friction is when trying to push a heavy object on a rough surface where the friction makes it difficult to move the object smoothly.
The fact that you can walk without sliding is an example of friction.
By definition, favorable is: expressing approval, giving consent, helpful, encouraging, advantageous. To be the most favorable would then mean the most approving, helpful, encouraging (& so on). Example: "a most favorable wind", "I've just received the most favorable answer".
This is the example of Newton third law and law of inertia.
ethos
Sliding your hands together is an example of sliding friction.
