There are many different materials-things- around us like
Anything-any object- around us is a matter
For example: Pen, cloth, fruits, cars, pencil, book…etc.
- Matter: is anything that has a mass and volume
or
it is everything that has a Mass and occupied a part of space.

Note
To deal with matter we need to know-measure- its length, mass & volume.

- Mass: is the amount of matter that the object contain
‫الكتلة‬‫مقدار‬ ‫ىه‬:‫مادة‬ ‫من‬ ‫الجسم‬ ‫يحتويه‬ ‫ما‬
Note That: Mass of ice-cream 1 > 2 > 3 is larger than mass of 2&3 why??
Because it has more matter-ice-cream- in it than in2 or 3
and also ice –cream 2= 4 because they have the same amount of ice cream in them

Volume of box 2 is bigger than volume of box 1 why??
Because box 2 occupy more space than box 1

Like gold and chemicals in lab
2- Kilogram (Kg)
It is used to measure large masses.
like fruits and vegetables
Ton.
To measure very large masses.
like cars
Measuring tools Measuring units:
1 kilogram (kg) = 1000 gram (g)
1 Ton = 1000 kilogram (kg)

When a body is submerged in a cylinder full of liquid completely, an amount
of the liquid is spilled out from the cylinder
The volume of the body = the volume of the spilled water
