Matter
The balance tell you the mass in?
Grams or kilograms.
What is the formula of density?
Density = Mass/Volume
What is gravity?
Gravity :a downward force which pushes down on the object
What is weight?
Weight is the meassure o the force of gravity on matter.
What is colour?
Objects or substances can be different colours or diffirent
shades of colours
name the two things that are important to average
density.
The steel the ship is made of.
And the air that is trapped in the body of the ship.
What is volume?
olume is the amount of a space an object or substances
occupies.
A measuring jug. Or a gradoated cylinder can be usted to
measure volume in âMLâ or âLâ.
Name the two things that are important to average
density
The steel that the ship is made of.
And the air that is trapped in the body of the ship.
Why do some objects float and other sink?
The reason why some objects float in water (or in other
liquids),while other sink, is because of density (mass per
unit of volume )and two opposite forces :gravity and buyancy
What si matter?
If something exist,has mass and occupies space,it is matter
.Matter is all around us.It is things we can see, like a tablet
,thing we cannot see, such as gasses like oxygen ,or things
we can taste, for example orange juice.
What is elasticity?
This is the ability of a soild object or subtance to return to
its original shape after removing the force which deformed
it for example, applying pressure to a spring.
Explain the formula of volume of an irregular object.
Final water volume (M) initial water volume (ML)= volume (
ML)
How classify mater.
Pure subtances , such siluer , which only consist of one type
of matter.
Mixtures which are made up of twoo or more pure
subtances. They can be hmogeneos, such as sea water, or
heterogeneous, like sand.
Explain colour ,hardness and magnetic properties
Colour:Objects or substances can be different colours or
different shades of colour.
Hardness: hardness is the measure of how resistant to
preassure or scratching an objects is.
Magnetic properties: magneticsm is the ability of cortain
substances to attract metals
Explain the formula of volume of a regular object.
Make measurement use this formula: Lenght (cm) x width
(cm)=volume (cm3)
