The document discusses matter, volume, mass, and weight. It defines matter as anything that takes up space and has mass. Volume is the amount of space an object occupies. Mass is the amount of matter in an object and remains constant regardless of location, while weight depends on gravitational force and can vary depending on location. Weight is measured with a spring scale in Newtons, while mass is measured with a balance in grams.

1. MATTER AND VOLUME
 Matter: anything that has mass and takes up
space
 Volume: amount of space an objects occupies
(characteristic of matter)
 No two objects can occupy the same space at the
same time

2.  Meniscus: curved surface of any liquid in any
container
 Lowest point of the meniscus is the accurate
measurement of volume

3. MATTER AND MASS
 Mass: the amount
of matter in an object
(characteristic of
matter)
 The mass of objects
are the same no
matter where the
object is in the
universe
 The only way to
change mass is to
change the amount of
matter the object is
made of
 Mass and weight are NOT
THE SAME

4.  Weight: a measure of the gravitational force exerted
on an object
 Gravitational force depends on the objects mass and
it’s relationship with a source of gravity
 The more mass, the more gravitational force, the
more weight the object has
 Objects weight is determined
by the force of gravity,
no gravity, no weight

5. DIFFERENCE BETWEEN MASS
AND WEIGHT
 Mass
 Measure of the amount of
matter in an object
 Always constant
regardless of location in
universe
 Measured by balance
 Units expressed in grams
 Weight
 Measure of gravitational
force on object
 Varies depending on
objects location in the
universe
 measured using spring
scale
 Units expressed in N
(Newtons)

6. Objects can have the same volume but very
different masses thus the gravitational force
would be greater causing greater weight
Inertia: tendency of an object to resist a
change in motion (Newton’s 1st
Law of
Motion)

7. NEWTON’S 1ST
LAW OF MOTION
Objects at rest will remain at rest and objects
in motion will remain in motion at a constant
speed and direction unless act on by an outside
force
Mass is a measure of inertia
The more mass an object has the harder to get
it moving and the harder it is to stop
Think train and car!!!
