Write two differences between mass and weight on the basis of their definition and si unit ?
Answers
Explanation:
Mass and weight are some of the common terms we come across in our everyday life. These terms are also confusing to many students new to physics. It is important to understand their meaning and how they differ with each other.
A mass of an object is the amount of matter contained by the object. The mass of an object does not change with location. For example, if the mass of an object is 10kg in earth, the object will have the same mass in moon.
The symbol for mass is m while the standard unit of measurement is kilogram.
Alternatively, weight of an object is the mass of the object acting upon by force of gravity. Since weight is a force, its standard unit of measure is in newton.
Just like mass that is independent of location, the weight of an object depends on the amount of force of gravity being acted upon the object. This implies that the weight of an object in earth will differ in moon since different amount of force of gravity acts on it.
The weight of an object is determined by multiplying the mass with acceleration of gravity.
W = m x a (N)
Another important phenomenon that is worth mentioning is weightlessness. Weightlessness is regarded as a state of free fall. Basically, the weight of an object depends on the mass and force of gravity which is supported by an object. If the supporting object is removed, weightlessness can be achieved.

Answer:
See, everything has mass, ok take this example
Explanation:
In space we feel 0 gravity which is also called weightlessness . This doesn't mean that all the remains in our body has left and we don't have our body with us.
It just means that the gravity is not acting on us and we do not feel our weight.
Fact: We would weigh different on North pole than on Equator.
OK! , IN EASY WORDS, Whenever gravity pulls our mass , it is called weight. And our weight would different on other planets but our mass is constant.
Hope it's helpful.
