Definition of mass
The quantity of matter in an object
S.I unit of mass
Kilogram (kg)

Inertia (1)
Is the natural tendancy of an object to resist any change in its original state, whether at rest or in motion
Inertia (2)
Inertia is not a physical quantity
Inertia (3)
Inertia cannot be measured
Inertia (4)
Inertia has no value
Inertia (5)
Inertia has no unit

States that an object will remain in its original state that is being at rest or in motion with constant speed (in a straight line) if no external forces acts on it
Example of inertia (1)
- When the cardboard is pulled quickly, the coin will fall into the glass - The inertia of the coin will maintain the original state of the coin that is being at rest
