Observing the variation of friction. Push a heavy box which is kept on

1.	Observing the variation of friction. Push a heavy box which is kept on a floor. The box does not move. Now increase the applied force until the box moves.The heavy box starts movinga) Why does the box does not move at first?b) When does the box tends to move?
Answer» a) The applied force is less than frictional force (static friction). b) When the applied force is more than static friction.

What is static friction?
Adjacent experiment representsA) Understanding the nature of friction and the concept of static frictionB) Observing variation of friction C) Effect of area of contact of frictional area D) None of the above
Write any one precaution which was taken by you while doing the experiment to understand the nature of friction.
A block of 1 kg is stopped against a wall by applying a force F perpendicular to the wall. If `mu=0.2` then minimum value of F will beA. 980 NB. 49 NC. 98 ND. 490 N
A block weighs W is held against a vertical wall by applying a horizontal force F. The minimum value of F needed to hold the block isA. Less than WB. Equal to WC. Greater than WD. Data is insufficent
The length of a simple pendulum of 0.4 m. The bob of the pendulum is drawn aside till the string is horizontal, it is then released from this horizontal position, What will be its velocity when it reached the lowest point in its swing ? `(g = 9.8 m//s^(2))` [Hint : Loss in potential energy = gain in kinetic energy]
If the system if Figure 7.13 is released from rest in the configuration shown by solid lines, find the maximum distance `h` through which the weight will fall. (Neglect friction and masses of pulleys) What will happen if `P = 2Q` ? [Hint : Apply work-energy theorem to the compound system consisting of the three masses and ceiling. To find intantaneous velocities of the masses apply the condition that the length of the string remains constant. Also remember that gravitational pulls are the lone forces external to the system, the tension of the string and pull the internal force ceiling are of the system]
A body moves in a straight line under the action of a variable force which changes with displacement of the body as shown in the figure. What is the work done when the body has been displaced through (i) 0.2 m, (ii) 0.4 m ?
Two masses 1.65 kg and 3.30 kg are joined together by a massles rod parallel to an incline to `30^(@)`, over which both slide down, with the 1.65-kg mass trailing behind the 3.30-kg mass. The coefficient of friction between the first mass and the plane is 0.226 and that between the second mass and the plane is 0.113 Find (a) the tension in the rod, (b) the common acceleration of the two masses [Hint : Make free-body diagram of the two bodies and consider their motion along and perpendicular to the plane]
