Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which statement about mass is correct?
A
A mass of 10 kg weighs 1 N near the Earth’s surface.
B
Mass is a gravitational force.
C
Mass increases when the gravitational field strength increases.
D
The greater the mass of a body, the more it resists a change in its motion.
Explanation: 

Detailed explanation-1: -Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion.

Detailed explanation-2: -Complete answer: Mass is a fundamental quantity and has the SI unit of kilogram (kg). 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.

Detailed explanation-3: -Greater the mass, greater is the inertia of the body.

Detailed explanation-4: -Assertion :Mass is a measure of inertia of the body. Reason: Greater the mass, greater is the force required to change its state of rest or of uniform motion. Q. Inertia is the property of a body which preserves its state of motion or uniform motion in a straight line.

Detailed explanation-5: -A body of greater mass has more inertia, hence a stone has more inertia.
