Depending on the roughness or smoothness of the surface, it will increase friction if it is rough,(which has more microscopic hills and valleys). If the surface is made of a smooth material, it will decrease friction
Friction belongs in between two contacting surfaces
Frictional force is the force that opposes motion between two surfaces.
When a ball accelerates down a hill, it experiences both kinetic friction (friction between moving surfaces) and rolling friction (resistance between the rolling ball and the surface). These two frictions oppose the ball's motion and affect its speed as it moves downhill.
mechanical friction is when two mechanics create friction
Force pushing two surfaces together
Factors affecting kinetic friction include the nature of the surfaces in contact, the roughness of the surfaces, the normal force pressing the surfaces together, and the presence of any lubricants or contaminants on the surfaces. Additionally, the temperature of the surfaces can affect kinetic friction.
Frictions
mass and velocity
The factors that affect the frictional force between two objects are the nature of the surfaces in contact, the normal force pressing the surfaces together, the roughness of the surfaces, and the presence of any lubricants or contaminants between the surfaces.
The two factors that affect the magnitude of friction are the nature of the surfaces in contact and the normal force pressing the surfaces together. Friction is stronger when the surfaces are rough and when the normal force increases.
The two factors that affect frictional force between two surfaces are the type of material of the surfaces and the force pressing the surfaces together.
maybe it could be something related to the universe
