What is Matter? Chapter 2 Section 1
Matter What do all of these objects have in common? These objects all have volume and mass. Matter - is anything that has volume and mass
Matter has Volume Volume – the amount of space that something occupies or the amount of space that something contains An objects volume is the amount of space the object take up Objects with volume cant share the same space at the same time
Measuring Volume of Liquids Meniscus – the curve at a liquids surface by which you measure the volume of a liquid To measure volume correctly, read the scale at the lowest part of the meniscus at eye level.
Measuring Volume of Solids Expressed in cubic units (m 3 or cm 3 ) Cubic means having three dimensions
Comparing Solids and Liquids You are able to compare liquids and solids because 1mL = 1cm 3
Measuring 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.
Matter has Mass Mass – 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
Gravity Gravitational force is large between objects with large masses that are close together.
Gravity Gravitational force is smaller between objects with smaller masses that are close together than between objects with large masses that are close together.
Gravity An increase in distance reduces gravitational force
Weight Weight – a measure of the gravitational force exerted on an object Newton (N) – the SI unit of force
The Difference Mass is: –A measure of the amount of mater in an object –Always constant for an object no matter where the object is in the universe –Measured with a balance –Expressed in Kilograms (kg), grams (g), and milligrams (mg). Weight is: –A measure of the gravitational force on an object –Varied depending on where the object is in relation to the Earth –Measured with a spring scale –Expressed in newtons (N)
Inertia Inertia – the tendency of all objects to resist any change in motion An object at rest will remain at rest until acted on An 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
