Question

As weight of object is force with which it gets attracted towards earth, whereas mass is the
amount of matter containing in body and it remains constant all over the universe. Weight of
an object on moon is 1/6 th of its weight on earth. The value of weight depends on
acceleration due to gravity.
a) The weight of an object of mass 5 kg on earth is
i) SN ii) 50 N iii) 49 N iv) None of these
b) Give any one point of difference between mass and weight.
c) An object has weight equal to 48 N on surface of earth. Calculate its weight on moon
d) Which is a vector quantity : Mass or weight ? Justify your answer.
e) What is the SI unit of weight?​

Answer 1

Answer:

a) will be 49 N

b) mass is same all over the universe but weight depends upon the gravitational pull of the body in space.

c) The weight will be 8 N

d) Mass is the vector quantity because weight is not same all over of the same object but mass is same so it would be easy to calculate so if we calculate weight we also need to calculate the gravitational force of body which it is in so it will become intricate

e) The SI unit of weight is Kilograms but it will not be the SI unit forever it will be replaced it will be replaced if there is any shift of gravity in earth.
