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!!!
