It provides static friction, so the object cannot move until the static friction is overcome.
Kinetic Friction replaces Static Friction when an object is in motion.
Static friction. The frictional force is greater then the force applied, meaning the object can't move.
You increase the object's acceleration.
Neglecting friction, its speed will grow with the least acceleration. Considering friction, it may not move at all.
The force of friction ALWAYS acts in the direction exactly opposite to the directionin which the object is moving.If the friction force acted in the same direction as the object's motion, then youwould want to have as much friction as possible, because that would help youmove the object with less fuel.
Friction acts in the opposite direction that the object is moving or trying to move. The force of friction is calculated by multiplying the normal force of the object, usually mass times gravity, by the coefficient of friction.
Friction is an opposing force on an object, so it slows it down.
Gravity and friction
Friction force
Friction allows the object to move more easily.
Kinetic Friction replaces Static Friction when an object is in motion.
Friction will slow down the moving object
Friction will slow down the moving object
In any given case, friction can produce AT MOST a certain amount of friction; if the coefficient of friction is known, this can be calculated as the normal force multiplied by the coefficient of friction.The force necessary to move an object must, of course, be greater than this maximum friction.
Objects move on different surfaces by friction.
Sticking. An extra force is required to start the motion, above the force required to maintain motion.
If you wish to actually move an object, some other force on the object has to be greater than the force of friction.
