Matter, Particle and Weight:
Sol: Matter: Matter is anything which occupies space and have some mass, offers resistance to any stress, for example Iron, stone, air, Water.
Particle: A body of negligible dimension is called as particle. But a particle also has mass.
Mass: The properties of matter by which action of one body can be compared with that of another can be defined as mass.
m = ρ.v
Where,
ρ= Density of body
V = Volume of the body as ,
Weight: Weight of body is force with which body is attracted towards center of earth.
