What determines the amount of friction?
The roughness of the two objects coming in contact determines the degree of friction.
Describe two forces that can affect an objects velocity?
Friction and Gravity are the two forces that affects an object's velocity. Friction is caused by both air and the surface on which an object is moving. Gravity is caused by Earth.
What is friction affected by?
Weight and surface affect friction. The more mass an object has more friction that will occur ex:/ It would be harder to slide an elephant across a floor than a hockey puck. This is because the large amount of friction on the elephant would slow it down. The smoother the surface the less friction. ex:/ There will be more friction on a floor of sandpaper than there would be on a floor of ice.
How can you increase the amount of friction between your shoes and the ground?
by increasing the roughness of the ground or increasing the sole of the shoes
What are facts about air resistance?
What type of friction is air resistance?fluid friction. Air resistance is fluid friction. Air resistance occurs between the surface of a falling object and the air that surrounds it. Rolling friction occurs when a rounded surface moves over a solid and sliding friction occurs when a solid moves over another solid. Static friction occurs when a solid touches another solid but there is no movement.What two factors affect air resistance?size and shape. Size and shape are the two factors that affect air resistance. Air resistance works with surface area, so the more surface area, the more air resistance. Think about when you drop two pieces of paper: one crumpled and one flat. The crumpled one falls faster because there is less air resistance acting on the paper.
How does roughness of surface that are touching affect the friction between the surface?
the rougher the surface is, the more friction there will be
How does a surface affect friction?
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
How does the roughness of surfaces that are toughing affect the friction between the surfaces?
The rougher a surface is, the higher the coefficient of static and kinetic friction will be.
What factors affect the coefficient of friction between two surfaces?
Surface temperature, Weight of the object, Roughness of surface and the object
How does surfaces affect frictions?
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
Factors that affect the amount of friction?
1.nature of the substance and the surface (roughness or smoothness). 2.mass of the object.
What factors affect the force of friction between sufaces?
The frictional force is described by F = μR where μ is the coefficient of friction (the roughness of the surface) and R is the force the object exerts perpendicular to the surface.
What are the variables for friction?
Surface area, surface roughness, material composition are all factors.
What are the two factors that affect the friction force between two?
normal force acting between them and surface roughness or frictional value that is mieu.
How does the roughness of surfaces that are touching affect the friction betwen the surfaces?
The rougher the surfaces the greater the friction.
What are the main causes of friction?
the main causes of friction are molecular adhesion,surface roughness,and the plowing effect.
What are the two main factors on which friction depends?
roughness of surface explain.... please..
