Words to know

• Matter • Volume

• Meniscus

• Mass

• Gravity

• Weight

• Newton

• Inertia

Page 3: Pre obj 1

What is it?•MatterMatter : Any thing that has volume or mass.

•VolumeVolume: The amount of space taken up, or occupied, by an object.

How do you measure it?

• Liters (L) and milliliters (mL) are the units that are most used to express the volume of liquid.

• The use of a graduated cylinder aids in the measuring of liquids. The surface of the liquid is not flat.

• Meniscus: The curve that you see at

the liquid’s surface.

Solids

•The volume of any solid is expressed in cubic units.

•Cubic meters (m3) or cubic centimeters (cm3)

Gases

•When you measure a gas you need to know the volume of the container that it is in. If you know the volume of the container then you will know the volume of gas.

Mass

• Mass: The amount of matter that something is made of.

• What is the difference between Mass and weight?

• Gravity: a force of attraction between objects that is due to their masses.

• Weight: a measure of the gravitational force exerted on an object.

The Difference is. . .

Mass

• Measure of the amount of matter in an object.

• Always constant• Measured with a

balance• Expressed in

kilograms (kg), grams (g), and milligrams (mg)

Weight

• 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•Newton: The SI unit of force•Inertia: the tendency of all objects to resist any change in motion.
