I assume you mean static and kinetic friction. Static friction tends to be stronger and less predictable.
For example, if you start applying more and more force to a stationary brick lying on sandpaper, it is almost impossible to predict when it will begin to move. Once it is moving, however, you can get a pretty consistent estimate for how much drag the brick is experiencing (kinetic friction).
Modern cars have computers monitoring the brakes. If you slam on your brakes, the computer will loosen up the brakes to prevent you from skidding. This is because static friction is more effective than kinetic friction, and once you start skidding out you have lost most of your braking power.

The two types of friction you learned about in this lesson are?
The two types of friction are static friction, which acts between stationary objects, and kinetic friction, which acts between moving objects. Static friction is generally greater than kinetic friction.
What is static friction and kinetic friction?
Static friction is the friction between two objects that are not moving relative to each other (eg: a desk on the floor not moving), kinetic friction is the friction between two objects that are moving relative to each other (eg: a desk sliding on the floor)
What is the formula for the coefficient of kinetic friction?
The formula for the coefficient of kinetic friction is μk = Fk/N, where μk is the coefficient of kinetic friction, Fk is the force of kinetic friction, and N is the normal force. The coefficient of kinetic friction represents the level of resistance between two surfaces in contact while they are in motion.
The two common forms of friction between two sliding surfaces presented in this course are and kinetic friction.?
Static
How is static friction and kinetic friction differ from each other?
Static friction occurs when an object is at rest on a surface, preventing it from moving. Kinetic friction occurs when an object is already in motion on a surface, resisting its motion. Static friction is usually stronger than kinetic friction.
What is kinetic friction and sliding friction?
Kinetic friction is the friction that arises between surfaces in relative motion. Sliding friction is the friction that occurs when an object slides over a surface.
The two types of friction you learned about in this lesson are?
The two types of friction are static friction, which acts between stationary objects, and kinetic friction, which acts between moving objects. Static friction is generally greater than kinetic friction.

What is the coefficient of kinetic friction between aluminun and felt?
The coefficient of kinetic friction between wool felt and aluminum is about 0.24 to 0.26.
What is static friction and kinetic friction?
Static friction is the friction between two objects that are not moving relative to each other (eg: a desk on the floor not moving), kinetic friction is the friction between two objects that are moving relative to each other (eg: a desk sliding on the floor)
Diference between static and kinetic friction?
the static friction is the force of friction that keep an object at rest from movie and kinetic friction is the force of friction that tries to start a moving object
What is different between static friction and kinetic friction?
Between any two body surfaces in contact there acts an frictional force. A friction can operate between a given pair of solids, between a solid and fluid or between a pair of fluids. There are two types of frictional forces : kinetic and static friction. When two bodies in contact move with respect to each other , rubbing the surfaces in contact the friction between them is called kinetic friction. The directions of frictional forces are such that it opposes the relative motion. Friction forces can also act between two bodies which are in contact but not moving or sliding with respect to each other. The friction in such case is static friction.
What is the formula for the coefficient of kinetic friction?
The formula for the coefficient of kinetic friction is μk = Fk/N, where μk is the coefficient of kinetic friction, Fk is the force of kinetic friction, and N is the normal force. The coefficient of kinetic friction represents the level of resistance between two surfaces in contact while they are in motion.

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.
How is static friction and kinetic friction differ from each other?
Static friction occurs when an object is at rest on a surface, preventing it from moving. Kinetic friction occurs when an object is already in motion on a surface, resisting its motion. Static friction is usually stronger than kinetic friction.
Friction between two flat surfaces is distinguished as being either static friction or what friction?
