Friction
When two objects are rubbed together, friction is created. Friction is the force that resists the motion between two surfaces in contact. Rubbing two objects together can generate heat due to the friction produced between them.

Gravity is the attractive force that pulls all objects together. It is a fundamental force of nature that causes objects with mass to be attracted to each other.
Gravity is the force that causes all matter to be attracted together. It is a fundamental force that causes objects with mass to exert an attractive force on each other.
Gravity is the force that causes objects in space to be held together. It is a fundamental force of nature that governs the motion of celestial bodies, keeping planets in orbit around stars, and holding galaxies together.
When two sticks are rubbed together, the force that causes them to stick together is friction. As the sticks rub against each other, the surface roughness creates resistance, generating heat and adherence between the two surfaces.
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.
When two things are rubbed together, friction is produced. The force of friction occurs between the surfaces of the objects in contact and opposes the motion between them.
Gravity would be the most obvious answer. Does that help? If not, i can elaborate.
No, friction is not a type of gravity. Gravity is the force that attracts two objects toward each other, while friction is the force that resists motion when two surfaces are in contact with each other. Both are separate physical phenomena with different causes and effects.
The force that causes objects to move downward is gravity
