No. Friction is a function of Normal Force and the friction coefficient, nothing else.
the front boot of the car increases the friction on the car
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.
The force acting on an object increases the friction between the object and the surface it is on. As the force increases, the friction force also increases proportionally until it reaches a maximum value, called the limiting friction. This relationship is described by the equation: friction force = coefficient of friction * normal force.
With increased surface areas in contact, friction increases.
Friction typically increases when the mass increases because there is more force pressing the surfaces together. However, the type of surfaces and the force pressing them together also affect friction levels.
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.
Surface area
As speed increases, the magnitude of fluid friction also increases. This is because at higher speeds, there is more interaction between the moving object and the fluid, resulting in greater resistance and friction.
The size of a friction force increases with an increase in the normal force pressing the surfaces together. It also increases with a rougher surface texture and an increase in the coefficient of friction between the surfaces.
friction increases the amount of force necessary to do work
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.
The force of friction between two surfaces increases as the angle between the surfaces increases, up to a certain point. This is because the component of the force perpendicular to the surfaces (normal force) increases as the angle increases, which in turn increases the maximum force of static friction that can be applied. Beyond a certain angle, the force of friction decreases due to the decreasing normal force.
