When friction is createed between two objects, the objects create static electricity! :D
The two factors on which friction depends are as follows 1. Area of contact 2. Mass of object
Friction between two objects is caused by the microscopic roughness of their surfaces interacting. When the surfaces come in contact and try to move past each other, these rough surfaces create resistance that we perceive as friction. The amount of friction depends on the force pressing the surfaces together and the materials involved.
An example where friction is small between two objects is when a sled is placed on ice. The smooth surface of the ice causes very little friction between the sled and the ice, allowing the sled to slide easily.
When two solid objects are rubbed together, kinetic friction occurs. This type of friction opposes the direction of motion between the surfaces of the objects and is caused by the microscopic interactions between the surfaces. The rougher the surfaces and the greater the force pressing the surfaces together, the stronger the kinetic friction.

that is friction
The two factors on which friction depends are as follows 1. Area of contact 2. Mass of object
Static friction occurs between two objects that are not moving relative to each other and prevents the objects from sliding against each other.

The friction between 2 objects makes them squeak
The amount of gravitational force between two objects depends on their masses and the distance between them. The force increases with the mass of the objects and decreases as the distance between them increases.

The amount of force between two charged objects is influenced by the magnitude of the charges on the objects and the distance between them. Increasing the charge of the objects or decreasing the distance between them will result in a stronger force of attraction or repulsion.
The force that keeps two objects from moving freely is called friction. Friction is the resistance to motion when two surfaces are in contact with each other. It acts in the opposite direction to the applied force and helps prevent slipping or sliding between the objects.
Static and Kinetic friction, static is the friction between two objects when they are not moving (relative to each other) an example of this is and object staying still on a sloped surface. obviously, kinetic friction is the friction between two objects that are moving and making contact, for example wind resistance.
