A frictional force is an important property associated with the motion of the substances and cannot be eliminated, however the frictional forces acting on the body may be mitigated with the use of lubricating fluids or gels that can make the surface slippery. In general, a frictional force exist...
Law 3. The frictional force depends on the surfaces in contact and its limiting value is directly proportional to the normal reaction between the surfaces. The coefficient of static frictionμs is the ratio of the limiting frictional force F to the normal reaction N: (5.6.1)μs=FN The coef...

In the above question, the frictional force on the cylinder is AF/3 towards right BF/3 towards left C2F/3 towards right D2F/3 towards leftSubmit Choose the correct option for each question. There is only correct response for each question. The frictional force depends on the nature of ...
adhesive friction,traction,grip- the friction between a body and the surface on which it moves (as between an automobile tire and the road) resistance- any mechanical force that tends to retard or oppose motion 3.friction- effort expended in moving one object over another with pressure ...
Law 1. The frictional force is always in such a direction as to oppose relative motion and is always tangential to the surfaces in contact. • Law 2. The frictional force is independent of the apparent areas of the surfaces in contact. • Law 3. The frictional force depends on the su...
Thefrictionalforce between a particle and fluid counterbalances the weight of the particle. 颗粒与流体之间的摩擦力与其重量相平衡. 辞典例句 In severe creasing thefrictionalresistance plays only a minor role in determining the crease resistance.
the frictional force depends on the coefficient of friction of the surfaces in contact and the normal force between objects. In other words, the frictional resistance between the book and the table in this example depends on the weight of the book and the roughness of the surfaces. As the bo...

The curl of the force must be zero since a conservative force cancels itself back out as the particle goes in a closed loop. $$\begin{align*} \bigtriangledown F=0 \end{align*} $$ A force is conservative if the integral of the work on a closed-loop is zero, ...
