5. Properties of matter
• Matter has dimensions, that means that
two pieces of matter cannot occupy the
same space.
Example: Two persons cannot sit in the
same chair.
6. • Intertia is the resistance of mass to a
change in its state of motion.
• Inertia is the way in which we measure
mass. If a body has double the mass of
another, it has double the inertia too.
For example: The Inertia of a car is
BIGGER than that of a shopping cart
because the car has more mass.
Properties of matter
7. Wich one is easier to move?
A shopping cart A car
The Inertia of a shopping cart is smaller than
that of a car.
8. • Gravitation is the attraction between
two objects.
• Is the force responsible of the fall of
objects, the movements of planets, and
the existance of tides.
Properties of matter
9. • Gravitation is another way in which we
measure mass. For example: the mass
of Jupiter is 310 times BIGGER than the
mass of Earth.That means that Jupiter
has more gravitation than Earth.
10. • Mass is related to the amount of matter.
• Can be measured according to the inertia
and gravity of the matter.
• The Mass of an object remains the same
always at any place.
• Weight is the force which a given mass
feels due to gravitation.
Mass and Weight are NOT the same!
All About Mass
11. If you go to the Moon, what changes?
Your weight or your mass?
The mass always stays the same. Your weight changes!
12. • Density is the relationship between the
mass and volume of a body.
• Density= Mass/Volume
All About Density
A body can be BIG but
have less mass.
A body can be small but
have more mass.
13. Bodies and systems of matter
• The objects that surround us and have definite limits
are called bodies of matter.
Example: A rock.
• Things with limits that are not precise are called
systems of matter
Example: A forest.
14. Wich object has definite limits?
Wich object has limits that are not
precise?
A tennis ball has definite limits. That means that it is
a body of matter.
A beach has limits that are not precise. That means
that it is a system of matter.
15. Observing the material word
• There are two scales in wich the
material world is observe.
– Macroscopic observation: Can be
percieved by our senses without the
help of instruments.
– Microscopic observation: Cannot be
percived by our senses without the
help of instruments.
16. Wich one is Macroscopic?

A plant A cell
