1) Mass is a measure of the amount of matter in an object and remains constant, while weight is the force exerted on an object by gravity and can vary depending on location.
2) Inertia is an object's resistance to changes in motion, and is directly proportional to its mass. Heavier objects are harder to speed up or slow down.
3) Density is a measure of how concentrated mass is in a substance or object, calculated as mass divided by volume. It can be used to determine if objects will float or sink in liquids. Various tools like balances and measuring cylinders are used to determine mass, volume, and density of objects.

Matter is anything which occupies space and has mass.
There are three states of matter:
1.solid
2. Liquid
3. Gas
Volume is an important quantity which is useful in the calculation of the density.

The Earth pulls all objects to its centre. This pull is called the force of gravity or gravitational force.
The weight of an object is the pull of the Earth on the object.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Weight massdensity
1.
2. • Mass:
As an object is moved around the Earth it is the
same object, made of the same molecules in the
same order and that something about it remains
constant. This is the amount of matter or “stuff”
it contains.
This unchanging quantity is called the mass and
is measured in kilograms. It is the quantity one
is usually interested in when buying, say, fruit or
vegetables.
3.
4. 4b. State that mass of a body resists change
from its state of rest or motion.
• mass determines how difficult it is to change the
motion of a body (e.g. to speed it up) and that is
because it determines the inertia of the body.
• Its here we will talk about inertia:
• Inertia: is the resistance of any physical object to a
change in its state of motion or rest, or the tendency
of an object to resist any change in its motion. It is
proportional to an object's mass.
5. • Lets have a look at a video to understand this
concept:
6. • Weight:
The weight of an object is the force of gravity
on the object and may be defined as the mass
times the acceleration of gravity, w = mg.
Since the weight is a force, its SI unit is the
newton.
7. 4c. State that a gravitational field is a region in which a
mass experiences a force due to gravitational
attraction.
Gravity Fields
A field is a region in which a force is felt.
Gravity is a very mysterious force. Nobody knows why objects
have this attractive force between them, even if they are far
apart. This attraction occurs for any object with
mass, however small. The force is very small, and always
attractive. We never get a repulsive gravitational force.
8. • As an object journeys around the Solar System, the force of
attraction to the nearest planet changes with the planet’s
proximity and mass.
• On Earth this force is approximately 10 N for every kilogram of the
object’s mass. Emphasise that it varies according to height above
sea-level (the actual value is between 9.79 N/kg and 9.83 N/kg).
• At this stage an appropriate “definition” of the Newton is “the
weight of an average apple” – use a fruit or vegetable that the
pupils will be most familiar with.
• If the mass of 1 APPLE IS 20 GRAMS, WHAT DO YOU THINK WOULD
BE ITS WEIGHT IN NEWTONS; (taking g=9.81m/s2)
9. 4(d) Calculate the weight from the equation:
weight = mass x gravitational field strength.
• Mass of 15 kg,
2
• Weight=15 Kg x 10m/s =150 N
• Mass 100g
• 100g100/1000=0.1 Kg
• Weight=0.1 Kg x 10=1 N
• Weight mass comparison
10. 4e. Explain that weights, and therefore
masses, may be compared using a balance.
• Emphasize that lever-arm balances compare unknown
weights/forces with the weight of a known mass. This is
equivalent to comparing masses since W = mg. Would such a
balance be accurate on the Moon?
• No, as g constantly changes.
11. 4f. Describe how to measure mass and weight by
using appropriate balances.
Spring balance:
• A spring balance is used to weigh things. An object placed
on it will compress or bend a spring to a degree that depends
upon the amount of weight, which can thereby be measured.
The typical bathroom scale is an example of a spring balance.
• Spring balances measure the weight and deduce the mass assuming that
g = 10 N/kg. Is this a valid assumption on the Moon?
12. Mass can be measured by:
• Using an electronic balance:
13. Volume of Regular Solids
• Revise, volume=?
• Volume of a cube= l x l x l
• Volume of a cuboids= l x b x h
3
• Volume of a sphere= 4/3 () r
• Find the volume of the following:
2 5 cm
2 R=5cm 4
2
2
14. volume of a liquid?
Volume of Liquids:
• Recall SI unit of volume is m , another popular unit
3 3
is, cm , liters, milli liters.
• You usually hear that your nestle bottle that you put on
the dispenser is 20 liters, hence usually the volume of
liquids is represented in liters, while that of solids is
represented in meters cube or cm cube.
15. In order to measure volume of liquids,
we use a measuring cylinders.
16. • How do we measure the volume of bolts and pebbles and coins?
• In short, volume of irregular solids:
Ans.=
1. Fill half of the measuring cylinder with water.
2. Note down the reading (volume), V1
3. Immerse a pebble in the cylinder.
4. Note down the reading (volume), V2
5. Volume of pebble= V2-V1
You will notice that your volume is in ml, we will use our knowledge
3
that 1 ml=1cm
• Does immersion in oil give a different value?
• No! Since the change would remain the same in both liquids.
17. 4h. Describe how to determine the density of a liquid, of a
regularly shaped solid and of an irregularly shaped solid which
sinks in water (volume by displacement).
Density of Regular Solids:
Calculate Mass:
Use one of the apparatus to compute the mass of regular objects:
1. Spring balance (weight mass)
2. Lever arm balance (weight mass)
3. Electronic balance (mass)
Calculate Volume: using formula if you know it!
Calculate Density:
3
Density=Mass/volume= kg/m
(in proper SI units)
18. Density of irregular solids:
Calculate Mass:
Use one of the apparatus to compute the mass of irregular objects:
1. Spring balance (weight mass)
2. Lever arm balance (weight mass)
3. Electronic balance (mass)
Calculate Volume:
By immersing them in measuring cylinders as discussed.
Calculate Density:
Density=Mass/volume= kg/m3
19. Density of Liquids:
Calculate Mass:
1. Take a measuring cylinder and measure its mass using: Spring balance, Lever arm
balance, Electronic balance
2. Fill it with the liquid in question
3. Measure the mass of the filled cylinder just the way you did in step 1.
4. Subtract the value obtained in step 3 with the value obtained in step 1.
5. This is your mass.
Calculate Volume:
Measure the volume using a measuring cylinder.
Calculate Density:
Density=Mass/volume= kg/m3
20. • Summing up
• Foam Led bar
3 3
• Volume=30cm Volume=30cm
• Density= ? Density= ?
• Same or Different?
• Different because mass is different.
Measuring cylinders: http://www.saburchill.com/chemistry/chapters/chap0021.html 4g. Describe how to use a measuring cylinder to measure the volume of a liquid or solid.
