Mass is defined as the measure of the inertia or the amount of substance.
It is measured in the units of Kilogram (Kg) or grams (g). (1 Kg = 1000 g)
Mass is measured using a balance. (Electronic or beam balance)
Gravitational Field:
A region in space around a mass where another mass experiences a
gravitational force.
Field lines are used to represent gravitational field and the direction
of force on any object within this field, as shown below:
The distance between the field lines represent its field strength.
The closer field lines are together, the greater will be the field
strength and vice versa.
, Weight is defined as the gravitational pull of the Earth on an object.
It is measured in the unit of N (recall that weight is basically a
downward force)
Weight can be measured using a Newton Meter or a Spring Balance (also
called a forcemeter).
Volume is the amount of space occupied by an object.
It is measurd in the units of m or cm
Volume can be measured with a measuring cylinder.
Volume of regular objects can be calculated using their formulas:
General formula: V = A H
Cube: l
cuboid: l b h
cylinder: r h
