What happened to the coefficients of friction as the surface area of the contact increases?
As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.

What happened to the coefficients of friction as the weight increased?
Nothing. The coefficient of friction is constant, as it is dependent on the surfaces that are interacting. Normal force increases as an objects mass increases (Be careful with the word "weight", as it denotes the effect of gravity) in a constant gravitational field. This normal force is what causes an increase in friction.
What happened to the coefficients of friction as the surface area of the contact increased?
As the coefficient of friction is not function of the area or not related to the area of the contact surface so the coefficient of friction remains constant on the increase of the contact area. The coefficient of friction depends upon the material of the friction surfaces only.
How friction increased?
With increased surface areas in contact, friction increases.
In what ways friction can be increased?
Friction can be increased by increasing the roughness of the surfaces in contact, increasing the force pressing the surfaces together, or using materials with higher coefficients of friction. Additionally, increasing the surface area in contact can also increase friction.
What two variables affect friction?
The two variables that affect friction are the surface roughness of the materials in contact and the force pressing the surfaces together. As the roughness increases or the force increases, friction typically increases as well.
How can friction be increased in a given situation?
Friction can be increased in a given situation by increasing the roughness of the surfaces in contact, increasing the force pressing the surfaces together, or by using materials with higher coefficients of friction.
What happened to the friction force as the weight or the pulled objects increased?
As the weight of the pulled object increases, the friction force also increases. This is because there is more contact between the surfaces, leading to greater resistance. The friction force is directly proportional to the normal force acting on the object, which increases with weight.
What pattern do you notice about the values for the coefficients of friction?
The coefficient of friction typically ranges from 0 to 1, with 0 indicating no friction and 1 indicating high friction. The coefficient of friction depends on various factors such as the surfaces in contact, surface roughness, and whether the surfaces are in motion or at rest. In general, smoother surfaces have lower coefficients of friction compared to rougher surfaces.
How can you increase the magnitude of friction between two surfaces How can you decrease the magnitude of friction?
To increase friction, you can increase the roughness of the surfaces in contact, increase the normal force pressing the surfaces together, or use materials with higher coefficients of friction. To decrease friction, you can use lubricants to reduce surface roughness and create a barrier between the surfaces, reduce the normal force acting on the surfaces, or use materials with lower coefficients of friction.
Which things causes low friction?
Smooth surfaces, lubricants, and reducing the contact area between two objects are factors that can cause low friction. Additionally, using materials with low coefficients of friction such as Teflon can also help reduce friction.
Will friction increase or decrease when an incline increases?
Friction will generally increase as the incline increases. This is because the normal force acting on the object will also increase with the angle of the incline, resulting in greater friction between the surfaces in contact.
What are the factors which affect the force of friction?
Friction equals the coefficient of friction times the normal force. Friction increases as the roughness of the materials increases. It also increases as the force pushing the materials together increases.
