Select the appropriate options and complete the following paragraph (Velocity, independent, initial velocity, dependent, gravity, friction, final velocity , direction ) The motion of any object under the influence of the force of ______ alone is called as free fall. During free fall, there will be no change in the ______ of motion of the object. But there will be a change in the magnitude of ______ of the object due to the gravitational pull of the earth . The acceleration that an object experiences during free fall is ____ of the mass of the object undergoing motion. when a body is dropped freely from a height, its ______ is zero. Whereas when a body is thrown vertically upwards, its ________ is zero .

Answer the following : When big grain storage container is required to slide on the ground , it becomes easier if two persons push it rather than one person . When the force is applied by both in the same direction , the movement is easy . You may have experienced this . what do we understand from this example ?

Two forces F_1 and F_2 act on a thin uniform elastic rod placed in space. Force F_1 acts at right end of the rod and F_2 acts exactly at centre of rod shown (both forces act parallel to length of the rod). F_1 causes extension of rod while F_2 causes compression. F_1 and F_2 both cause extension of rod. F_1 causes extension of rod while F_2 does not change length of rod. The correct order of True (T) or False (F) statements is

Oral work : How much force will be applied on mass of 1 kilogram on a surface with no friction if it is pulled with acceleration of 1 m/s^2 ?

Statement-1 : Two soild sphere of radius r and 2r , made of same material, are kept in contact. The mutual grvitational force to attraction between them is proportional to 1//r^(4) . Statement-2 : Gravitational attraction between two point mass bodies varies inversely as the square of the distance between them.

Choose the correct options The rough surface of a horizontal table offers a definite maximum opposing force to initiate the notion of a block along the table, which is the motion of a block along the table, which is proportional to the resultant normal force given by the table. Forces F_1 and F_2 act at the same angle theta with the horizontal and both are just initiating the slide motion of the block along the table. Force F_1 is a pulling force while the force F_2 is a pushing force. F_2>F_1 , because

A wooden box lying at rest on an inclined surface of a wet wood is held at static equilibrium by a constant force vec F applied perpendicular to the incline. If the mass of the box is 1 kg, the angle of inclination is 30^(@) and the coefficient of static friction between the box and the inclined plane is 0.2, the minimum magnitude of vecF is (Use g= 10m//s^(2))

This question has statement 1 and statement 2 . Of the four choice given after the Statement , choose the one that best describe the two Statement . If the spring S_(1) and S_(2) of force constant k_(1) and k_(2) respectively , are streached by the same force , it is found that more work is done on spring S_(1) then on spring S_(2) Statement -1: If statement by the same answer work done on S_(1) work on S_(1) is more then S_(2) Statement - 2 : k_(1) ltk_(2)

Check the correct statements on scattering of light S1 : Rayleigh scattering is responsible for the bluish appearance of sky S2 : Rayleigh scattering is proportional to 1//lambda^(4) when the size of the scatterer is much less than lambda S3 : Clouds having droplets of water (large scattering objects) scatter all wavelengths are almost equal and so are generally white S4 : The sun looks reddish at sunset and sunrise due to Rayleigh scattering

The electrostatic potential on the surface of a charged conducting sphere is 100 V. Two statement are made in this regard. S1: At any point inside the sphere, electric intensity is zero. S2: At any point inside the sphere, the electrostatic potential is 100 V. Which of the following is a correct statement ?
