Friction reduce the velocity, hence, it affect kinetic energy. The potential energy from static pressure is then drawn to maintain the velocity (transformation of potential -> kinetic energy). We then see the friction reduce the static pressure but actually, it affect kinetic first.

When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
A horizontal force of 40 newtons will just start a 600 newton empty sled moving across packed snow what is the coefficients of static and kinetic friction?
static friction= normal contact force*coefficient of static friction 40 = (600*9.8) * CSF CSF=40/(600*9.8) (you can calculate that yourself, i cant be bothered) there isn't enough info to work out the coefficient of kinetic friction
What is coeffitient of stactic n kinetic friction?
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.
What friction prevents an object from moving when a force is applied?
The friction produced that stops an object moving when force is applied is 'static friction'.
When you are performing work what are the two types of friction are acting upon?
There are only two types of friction and they are static and kinetic.
How is static friction and kinetic friction differ from each other?
They are different because static means "not in motion" and kinetic means "in motion". Kinetic friction means friction that is moving and static friction means friction that is not moving.
When a body slides over a surface the kinetic friction and static friction related as?
Kinetic friction is the friction that applies when an object is moving; static friction is the friction that applies when the object is not moving. Static friction must always be greater than, or equal to, kinetic friction.
What is the difference with static friction and kinetic friction?
static friction is the friction between two bodies they are in contact. And another sliding over the other. Kinetic friction is the friction between two bodies they are rolling .And that force is opposite to the rolling angle
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 friction is used when an object sits still?
Static friction resists an object from moving when at rest (still) with respect to the surface it is resting on or in contact with. Kinetic friction, or dynamic friction, (normally what we think of when we say 'friction') describes the friction that occurs when one body moves relative to another body and when both bodies are in contact with each other.
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)
Should one add static friction and kinetic friction together to find the total friction force?
No. You use whichever applies: if an object is at rest, you use static friction. If it is moving, you use kinetic friction.
When does static electricity happen?
When friction is created by two objects that are moving but not relative to each other, its called static friction. Static friction keeps an object from moving until friction is created to move it.
What are the 2kinds of friction?
Static Friction and Kinetic Friction. Static Friction is what friction that slows you down. While Kinetic friction is sliding friction.
As soon as an object starts moving what replaces static friction?
Kinetic Friction replaces Static Friction when an object is in motion.
Is kinetic friction the one that must be overcome in order to start something moving?
static
What is the difference between Static 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.
