Chapter 4 Mass,Weight & Density
Gravitational Field
A mass experiencing force due to gravitational attraction
known as weight
Density
Density S.I unit is in
Kilogram per cubic metre.
Subtopic
Density Formula is
density = mass/volume
Defined as mass per unit volume
Density is defined as its mass per unit volume.
Subtopic
Inertia
The reluctance of an ojbect to change its state of motion due to its mass
Mass is the measure of inerita
The greater the mass of an object,
the greater the inertia
Subtopic
Weight
Weight of an object is the gravitational force of gravity acting on it.
Weight S.I unit Newton
Formula:
Weight=Mass X Gravitational field strength
Vector Quantity
Measured using
Spring Balance
Compression Balancance

Mass
Mass is the amount of matter,in a body.
Mass is a measure of inertia.
Mass S.I unit Kilogram
It does not depend on the gravitational field strenth
Scalar Quantity
Measure using
Beam Balance
Electronic calibrated balance
