An object is at the top of a smooth sphere which is kept fixed. As object slides down after being given a negligible side push, magnitude of acceleration of object during its motion till it reaches ground.

As shown in the figure, a wedge of mass M is placed on a smooth inclined ramp that makes an angle theta to the horizontal. An object of mass m rests on top of the wedge. The sliding down the ramp at acceleration a. determine the apparent weight of the objects as it slides down. noth that there is friction between the object and the wedge so that the object remains relatively at rest on the wedge.

A particle mass m begins to slide down a fixed smooth sphere from the top of its vertical diameter. Calculate its tangential acceleration, radial acceleration and total acceleration when it breaks off.

A particle mass m begins to slide down a fixed smooth sphere from the top of its vertical diameter. Calculate its tangential acceleration, radial acceleration and total acceleration when it breaks off.

During uniform circular motion of object out of (i) magnitude of velocity (ii) magnitude of force (iii) acceleration (iv) momentum vector is not constant.

An object is placed on the surface of a smooth inclined plane of inclination . It takes time t to reach the bottom of the inclined plane. If the same object is allowed to slide down rough inclined plane of same inclination , it takes time nt to reach the bottom where n is a number greater than 1. The coefficient of friction  is given by -

A block slides down from top of a smooth inclined plane of elevation theta fixed in an elevator going up with an acceleration a_0 The base of incline has length L. Find the time taken by the block to reach the bottom.

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 .
