Static friction is more than sliding friction.

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

A : It is difficult to move a cycle along a road with its brakes on. R : Sliding friction is greater than rolling friction.

Assertion : It is difficult to move a cylce along the roda with its brakes on . Reason : Sliding friction is greater than rolling 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

Difference between Static friction and sliding friction

Define frictional force and explain it by taking an example. Plot a graph of frictional force against applied force and explain why kinetic friction is lesser than static friction

Assertion : Static friction is a self-adjusting force upto its limit mu_(s)N "where" mu_(s) is the coefficient of static friction. Reason: One can use the equation f_(s)=mu_(s)N only when the maximum value of static friction comes into play

Which is true for rolling friction ( mu _(r ) ) , static friction ( mu_(s)) and kinetic friction ( mu_(k)) ?

Static-friction is a self- adjusting force. Comment.
