The laws of dynamic friction describe the relationship between the force required to overcome friction between two surfaces in motion and the normal force acting perpendicular to those surfaces. These laws state that the force of friction is proportional to the normal force and is independent of the surface area in contact, while the coefficient of friction relates the force of friction to the normal force.

Explain the term dynamic limiting friction and rolling friction?
Dynamic limiting friction refers to the maximum amount of frictional force that can be generated between two surfaces in relative motion. Rolling friction is the resistive force that opposes the motion of a rolling object, which is typically smaller than sliding friction due to the rolling motion.
Friction between objects that are stationary is called what?
The friction between two stationary forces is called static friction. It is the friction that resists two objects to start moving against each other. Once in motion, the friction between two forces is called dynamic friction. Static friction tends to be greater than dynamic friction, which is why it takes more force to get a heavy box moving along the ground compared to keep it going.
What affect sliding friction?
Sliding friction is affected by the nature of the two surfaces in contact, the presence of lubricants or contaminants, the applied force pressing the surfaces together, and the smoothness of the surfaces.
If the coefficient of static friction is 0.75 what is the coefficient of dynamic friction?
The coefficient of dynamic friction is typically lower than the coefficient of static friction. It can range from 0.3 to 0.6 depending on the materials in contact. Without further information, we can estimate it to be around 0.4 to 0.6 based on common values.
Experiment to find coefficient of dynamic friction?
To find the coefficient of dynamic friction, conduct an experiment by placing a block on a flat surface connected to a force sensor. Apply a horizontal force gradually to the block until it starts to slide, and note the force required for motion to begin. Use the formula: coefficient of dynamic friction = (force to start motion) / (weight of the block) to calculate the coefficient. Repeat the experiment multiple times to get an average value.
What is the definition of dynamic friction?
Dynamic friction is a type of friction that is created when two objects are rubbing against one another. The amount of dynamic friction can change depending upon the speed of the two objects.
As soon as an object starts moving what replaces static friction?
Kinetic Friction replaces Static Friction when an object is in motion.
2 types of friction?
There is static friction, and dynamic (also called kinetic) friction.
Is fluid and dynamic friction the same?
No, it is not.
What is dynamic coefficient of friction?
n
State the laws of friction?
Sate laws of friction
What is dry friction what are the types of dry friction what is fluid friction what are the types of dynamic or kinetic friction?
Fluid friction is the friction that occurs when an object moves through a fluid or gas.
Is the coefficient of dynamic friction greater than the coefficient of static friction and why?
No, the coefficient of static friction is typically greater than the coefficient of dynamic friction. This is because it generally requires more force to initiate the motion of an object (static friction) compared to maintaining the motion of an object once it has started moving (dynamic friction).
What kind of friction allows you to walk without slipping?
Alternately, as we step: sliding, or dynamic friction; static friction; sliding friction again. Sequence repeats with each step.

Explain the term dynamic limiting friction and rolling friction?
Dynamic limiting friction refers to the maximum amount of frictional force that can be generated between two surfaces in relative motion. Rolling friction is the resistive force that opposes the motion of a rolling object, which is typically smaller than sliding friction due to the rolling motion.
