Will the speed of the object affect the amount of friction between object and the surface?
No. The speed of the object does not affect the amount of friction between an object and the surface. Friction is affected by the types of surfaces in contact, smoother surfaces produce less friction, and the weight of the object moving horizontally affects the resistance relative to the two surfaces in contact. Greater weight causes greater resistance.
What are the factors that determine the amount of friction between two surfaces?
Friction= Normal force* Coefficient of friction
How can the amount of friction between surfaces be increased?
push the object on a rough surfgace
Is friction high when you move a rock?
Assuming the two surfaces are the same, the amount of friction is proportional to the mass of the object, so the heavier the rock the greater will be the frictional force.
The amount of friction between the two surfaces depends upon the type of surface and what other factor?
The normal force between them.
Is the amount of friction greater between rough surfaces or smooth surfaces why?
Rough because it takes longer to slide and gets more friction

Greater weight causes greater resistance.
Is the amount of friction greater between rough surfaces smooth?
smooth surfaces have less friction, take an ice rink for example, the resistance on that is less than the resistance on asphalt
Is the amount of friction greater between rough surfaces or or smooth surfaces?
rough surfaces because it has more bumps that stop it from moving faster
What are the factors that determine the amount of friction between two surfaces?
Friction= Normal force* Coefficient of friction
What are the two factors that determine the amount of friction between two surfaces?
Friction= Normal force* Coefficient of friction
Describe the factors that cause static friction between two surfaces to increase.?
A higher coefficient of static friction increases the static frictional force. A greater normal force also does this.
How can the amount of friction between surfaces be increased?
push the object on a rough surfgace

Assuming the two surfaces are the same, the amount of friction is proportional to the mass of the object, so the heavier the rock the greater will be the frictional force.
Amount of friction depend on two thing?
The amount of friction between two surfaces depends on more than two things. It could depend on many things like The shared surafce area The amount of force between the objects How rough or somooth the surfaces are The presence of a lubricant or glue Ball bearings Even temperature. Many things affect the amount of friction between things
When might you want to increase friction between two object?
Turning wheels against surfaces would require some amount of friction.
A lower coefficient of friction indicates that the two surfaces in contact have less resistance?
Yes but make sure you are clear in your understanding between the coefficient of friction and the force of friction. The force of friction is the force that resists the motion of two surfaces moving against one another. The amount of friction is determined by the product of the coefficient of friction and the normal (perpendicular) force that is pressing the two surfaces together. The coefficient of friction is a unit-less constant, that indicates how two surfaces compare to two other surfaces that are being pressed together the same amount. If the normal force is the same on two pairs of surfaces the pair of surfaces with the lowest coefficient of friction will experience the lower force of friction.
