Which has a maximum value kinetic friction or static friction?
The maximum value of static friction is typically greater than the maximum value of kinetic friction. Static friction is the force required to overcome the initial resistance of an object at rest, while kinetic friction is the force required to keep an object in motion.
What happens to the kinetic friction force as the mass is increased?
The kinetic friction force remains constant regardless of the mass of the object. It is determined by the nature of the surfaces in contact and is independent of weight.
How speed and weight affect an amount of kinetic energy?
Kinetic energy is directly proportional to an object's speed squared, meaning that as an object's speed increases, its kinetic energy increases exponentially. Weight itself does not directly affect an object's kinetic energy, but it can impact the object's speed due to factors like friction and resistance. Ultimately, both speed and weight play a role in determining the kinetic energy of an object in motion.
What fricton occurs when a object rolls over a surface?
The friction that occurs when an object rolls over a surface is called rolling friction. It is generally lower than static or kinetic friction because the object's motion is distributed over a larger area during rolling. Rolling friction is dependent on factors such as the nature of the surfaces in contact and the weight of the object.
What is the difference between friction and weight?
Friction is the resistance to motion when an object moves across another surface, while weight is the force exerted on an object due to gravity. Friction depends on the roughness of the surfaces in contact and the force pressing them together, whereas weight depends on an object's mass and the acceleration due to gravity.
Which has a maximum value kinetic friction or static friction?
The maximum value of static friction is typically greater than the maximum value of kinetic friction. Static friction is the force required to overcome the initial resistance of an object at rest, while kinetic friction is the force required to keep an object in motion.

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.

Does friction affects the weight of an object?
no, friction just changes the motion of an object.
What is the coefficient of kinetic friction between the 13.0kg wooden crate and the horizontal force of 31N of the floor?
The coefficient of kinetic friction can be calculated using the formula: coefficient of kinetic friction = force of kinetic friction / normal force. The force of kinetic friction can be found using the formula: force of kinetic friction = coefficient of kinetic friction * normal force. Given the force of 31N and normal force equal to the weight of the crate (mg), you can calculate the coefficient of kinetic friction.
What is the difference between friction and weight?
Friction is the resistance to motion when an object moves across another surface, while weight is the force exerted on an object due to gravity. Friction depends on the roughness of the surfaces in contact and the force pressing them together, whereas weight depends on an object's mass and the acceleration due to gravity.
How do you find kinetic friction without the coefficient?
You can find the kinetic friction force by measuring the normal force acting on the object and the net force experienced by the object when it is in motion. By applying Newton's second law (F = ma), where a is the acceleration of the object, you can calculate the kinetic friction force without knowing the coefficient.
What are some ways to increasing friction?
Use a surface that has a higher coefficient of static/kinetic friction and/or add more force downwards on the object.
The amount of friction divided by the weight of an object forms a unitless number called the ... of friction?
coefficientThe amount of friction divided by the weight of an object forms a dimensionless number called the coefficient of friction.
Can friction or acceleration due to gravity affect the weight of an object?
Friction and acceleration due to gravity do not directly affect the weight of an object. Weight is determined by the gravitational force acting on the object, which is independent of these factors. However, friction can affect the apparent weight of an object on a surface by opposing the force of gravity.
