2Matter What do all of these objects have in common? These objects all have volume and mass.Matter - is anything that has volume and mass
3Matter has VolumeVolume – the amount of space that something occupies or the amount of space that something containsAn object’s volume is the amount of space the object take upObjects with volume can’t share the same space at the same time
4Measuring Volume of Liquids Meniscus – the curve at a liquid’s surface by which you measure the volume of a liquidTo measure volume correctly, read the scale at the lowest part of the meniscus at eye level.Show them.
5Measuring Volume of Solids Expressed in cubic units (m3 or cm3)Cubic means “having three dimensions”
6Comparing Solids and Liquids You are able to compare liquids and solids because 1mL = 1cm3
7Measuring the Volume of Gas Gas expands to fill its container, of if you know the volume of the container the gas is in, then you know the volume of the gas.
8Matter has MassMass – is the amount of matter that something is made of.Gravity – is a force of attraction between objects that is due to their masses.All matter has mass, therefore all matter experiences gravity
9Let check out whatTim and Mobyhave to say aboutGravity!!
10GravityGravitational force is large between objects with large masses that are close together.
11GravityGravitational force is smaller between objects with smaller masses that are close together than between objects with large masses that are close together.
12GravityAn increase in distance reduces gravitational force
13WeightWeight – a measure of the gravitational force exerted on an objectNewton (N) – the SI unit of force
14The Difference Mass is: Weight is: A measure of the amount of mater in an objectAlways constant for an object no matter where the object is in the universeMeasured with a balanceExpressed in Kilograms (kg), grams (g), and milligrams (mg).Weight is:A measure of the gravitational force on an objectVaried depending on where the object is in relation to the EarthMeasured with a spring scaleExpressed in newtons (N)
15InertiaInertia – the tendency of all objects to resist any change in motionAn object at rest will remain at rest until acted onAn object moving will remain moving at the same speed and direction unless something acts on it to change its speed or direction.Inertia increases as mass increase
