The document discusses the key differences between matter, volume, mass, and weight. Matter is anything that takes up space and has mass, while volume refers to the amount of space an object occupies. Mass is a measure of the amount of matter in an object and remains constant regardless of location, whereas weight depends on gravitational force and can vary depending on location. Mass is measured using a balance and expressed in grams, while weight is measured using a spring scale and expressed in Newtons.

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!!!
