Difference between Sliding friction and rolling friction

Differentiate between static and sliding friction.

Static friction is more than sliding friction.

A 60kg is pushed horizontaly with just enough force to start it moving across a floor and the same force continues to act afterwards. The coefficient of static friction and sliding friction are 0.5and 0.4 respectively the accleration of the body is

A 60 kg body is pushed with just enough force to start it moving across a floor and the same force continues to act afterwards. The coefficient of static friction and sliding friction are 0.5 and 0.4 respectively. The acceleration of the body is

Distinguish between sliding friction and rolling friction.

What is static friction?

A force of 750 N is applied to a block of mass 102 kg to prevent it from sliding on a plane with an inclination angle 30^@ with the horizontal. If the coefficients of static friction and kinetic friction between the block and the plane are 0.4 and 0.3 respectively, then the frictional force acting on the block is

Matching block type LIST - I (a) Two rotating discs are brought in contact coaxially (b) Contact force on a body placed in on rough surface (c ) To continue a motion is easier than to initiate the motion (d) For a Static friction less than limiting friction LIST - II (e ) Generated friction is equal to appliedexternal force in magnitude (f) Loss of Rotational KE is transformed partly to heat (g) The resultant of normal reaction and friction (h) Kinetic friction is less than static friction
