But still its effects could be tested On the other end there is no phenomena which can be explained on the basis

The statement above is true. Validity of this incisive remark can be validated from the example of moment of inertia. It states that the moment of inertia of a body depends on its energy. But according to Einstein’s mass-energy relation , energy depends on the speed of the body.
The Physical world around us is full of different complex natural phenomena so the world is in-comprehensible. But with the help of study and observations it has been found that all these phenomena are based on some basic physical laws and so it is comprehensible.
In which of the following examples of motion, can the body be considered approximately a point object :
Solution : (a) The size of a carriage is very small as compared to the distance between two stations. Therefore, the carriage can be treated as a point sized object. (b) The size of a monkey is very small as compared to the size of a circular track. Therefore, the monkey can be considered as
