Matter occupies 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. Mass is measured in kilograms and is a measure of an object's inertia, while weight is measured in Newtons and depends on gravitational pull.

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)
• 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 is 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

5. Difference between mass and
Weight
• Mass • Weight
• Measure of the amount of • Measure of gravitational
matter in an object force on object
• Always constant • Varies depending on
regardless of location in objects location to earth
universe (or other large body in
• Measured by balance space)
• Units expressed kg, g, • measured using spring
mg 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. • 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!!!
