Answer the following :
In the figure alongside , a string , attached to a wooden block on a table , is passed over a pully and tied to a weight . On applying a sufficient weight, the block will be seen to move :
What will happen on applying more force ?:

Answer the following : In the figure alongside , a string , attached to a wooden block on a table , is passed over a pully and tied to a weight . On applying a sufficient weight, the block will be seen to move : Which force is being applied here ?:

Answer the following : In the figure alongside , a string , attached to a wooden block on a table , is passed over a pully and tied to a weight . On applying a sufficient weight, the block will be seen to move : How can this force be increased ?:

Answer the following : In the figure alongside , a string , attached to a wooden block on a table , is passed over a pully and tied to a weight . On applying a sufficient weight, the block will be seen to move : When can we say that work is done by the applied force ?:

Answer the following : In the figure alongside , a string , attached to a wooden block on a table , is passed over a pully and tied to a weight . On applying a sufficient weight, the block will be seen to move : If the block moves forward we can say that it has been displaced . due to the displacement , we sat that the force has done some work . can we measure this work ?:

Answer the following : What happens to the pressure exerted on a given area if the force applied is doubled ?

Answer the following questions: What happens when a force is applied at right angles to the direction of motion if a body.

A block of mas M is resting on an inclined plane as shown in the figure. The inclination of the plane to the horizontal is gradually increased. It is found that when the angle of inclination is theta the block just begins to slide down the plane. What is the minimum force F applied parallel to the plane that would just make the block move up the plane ?

Answer the following question in one sentence each: What happens when a force is applied in the direction of body of a motion?

Answer the following question in one sentence each: What happens when a force is applied in the direction opposite to that of motion of the body?

Answer the following questions:Make two sufficiently long, identical tubes out of a cardboard. Arrange them on a table, in front of a wall as shown in figure . Place a clock near the end of one of the tubes and try to hear the ticking of the clock at the end of the other tube by placing your ear there. Adjust the angles of the two tubes till you can hear the sound very clearly Measure the angle of incidence theta_1 and the angle of reflection theta_2 . Try to see if they are related in any way. In the experiment, what will happen if you lift one of the tubes to some height?
