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.
