What are two sources of friction?
Not sure if you mean 2 types of friction. Two types of friction can be just friction with the ground, and air friction such as drag on any vehicle, or any type of flying machine. Other objects can have air friction too, but not as much as something moving at a higher rate of speed.
What is friction what are four types of friction?
Friction is the force that resists motion between two surfaces in contact with each other. The four types of friction are static friction (force between stationary surfaces), kinetic friction (force between moving surfaces), rolling friction (force between a rolling object and a surface), and fluid friction (force between an object moving through a fluid).
Is static friction and limiting friction the same?
Static friction and limiting friction are not the same. Static friction is the friction force that prevents an object from starting to move when a force is applied, while limiting friction is the maximum amount of friction force that can be exerted before the object starts sliding. Static friction can vary in magnitude, while limiting friction is a specific value for a given pair of surfaces.
The size of forces due to static sliding and rolling friction between two surfaces?
Static friction force is the force that opposes the initiation of motion between two surfaces and can vary in magnitude up to a maximum value. Rolling friction force is typically lower than static or sliding friction, as it involves the resistance to rolling motion. The specific forces depend on various factors such as the roughness of the surfaces, the magnitude of the normal force, and any lubrication present.
What type of friction is brushing your hair?
The friction experienced when brushing your hair would be considered dry friction, as it occurs between solid surfaces without any lubricating medium.
