Friction is a force that opposes the relative motion or tendency of such motion of two surfaces in contact. It acts parallel to the surfaces and is caused by the irregularities present on the surfaces in contact.
There are three main types of friction: static friction, sliding (kinetic) friction, and rolling friction.
1. Static Friction is the force that opposes the initiation of motion between two surfaces that are in contact and at rest relative to each other.
Static friction prevents the object from moving even when a force is applied. It adjusts itself to be equal and opposite to the applied force until the force reaches a critical value, known as the limiting friction. Once this critical value is exceeded, the object starts moving.
2. Sliding or Kinetic Friction: Sliding friction, also known as kinetic friction, is the force that opposes the motion of two surfaces sliding past each other. Once an object overcomes static friction and starts moving, sliding friction comes into play. It is generally weaker than static friction and remains relatively constant as long as the surfaces continue to slide past each other.
3. Rolling Friction: Rolling friction is the force that resists the motion of a rolling object, such as a wheel or a ball, on a surface. Rolling friction is generally lower than sliding friction, making it easier for objects to roll than to slide. It occurs because the object deforms slightly at the point of contact with the surface, and this deformation creates resistance.
In summary, static friction prevents the initiation of motion, sliding friction opposes the motion of sliding surfaces, and rolling friction hinders the motion of a rolling object. Understanding these types of friction is crucial in various fields, from physics and engineering to everyday scenarios where friction plays a role in the movement of objects.

I think the answer would be 8N because-- M= 2 KG W= mg = 2 KG*10 m/s² = 20N Coefficient of static friction= 0.4 therefore, 0.4*20N= 8N

[@rithizx]

HW : w= mg= N 2×10 = 20 N=> Nf Coefficient of static friction(mu) =0.4 fs = (mu)s× N = 0.4 × 20 = 8 N But, even the 4N is acting on the object but the fsmax will cancel the force because it is Self Adjusting Force and the force is the less than fsmax ... 😊

The frictional force is 8N. Therefore the applied force, 4N, is not sufficient to move the box.

the frictional force between the block and the floor is 4N, same as the applied force as the applied force is less than limiting frictional force

[@FazilVijay-et9md]

Solution is here Given Ms=0.4 Mass=2kg Applied force=4N Find force of friction Soln. N=W W=Mg =2x10=20 Msmax=MsxN =0.4x20 =8N Hence we need to produce more than 8N.but the Applied force is only 4N ,thus the object can not be moved.And answer for question =8N
