|
B Mass is measured in newtons
|
|
|
C Weight is a force.

|
|
D Weight is measured in kilograms.

Detailed explanation-1: -Only Weight is a force. C is incorrect, since as discussed above, they are totally different quantities so they do not have the same unit. Mass is kg, Weight is or N.
Detailed explanation-2: -The force has a SI unit of Newton (N). Hence from this we can conclude that, The unit of mass is kilogram and the unit of weight is Newton. Therefore the correct answer of the above question is option c.
Detailed explanation-3: -Mass is a scalar quantity and weight is a vector quantity whereas weight of an object is the force of gravity acting on it. Therefore mass is a scalar quantity and weight is a vector quantity.
Detailed explanation-4: -Mass is a fundamental measurement of how much matter an object contains. Weight is a measurement of the gravitational force on an object. It not only depends on the object’s mass, but also on its location. Therefore, weight is actually a measure of force.
