rough surfaces because it has more bumps that stop it from moving faster

Is the amount of friction greater between rough surfaces or smooth and Why?
The amount of friction is generally greater between rough surfaces because the irregularities on the surfaces create more points of contact and interlock, increasing resistance to motion. Smooth surfaces have less interlocking and contact points, resulting in lower friction.
Is the amount of friction greater between rough surfaces or smooth surfaces why?
Rough because it takes longer to slide and gets more friction
Will the speed of the object affect the amount of friction between object and the surface?
Yes, the speed of the object can affect the amount of friction between the object and the surface. In general, an increase in speed can lead to an increase in friction due to factors like heat generation and surface interactions. However, the relationship between speed and friction can vary depending on the specific conditions and materials involved.
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
What are the factors that determine the amount of friction between two surfaces?
The factors that determine the amount of friction between two surfaces include the roughness of the surfaces, the force pressing the surfaces together, and the types of materials involved. Friction increases with rougher surfaces, higher forces, and when the materials have a high 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?
The amount of friction between surfaces can be increased by using materials with higher coefficients of friction, applying greater force pressing the surfaces together, increasing the surface roughness, or by using methods like adhesives or using a lubricant with higher viscosity.
Is friction high when you move a rock?
Yes, friction is high when you move a rock because there are contact points between the rock and the surface that resist motion, generating 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.
