Ch.1 Sec.1 Introduction To Matter Flashcards
Anything that has a mass and takes up space. Anything in the universe that you can see is made up of some kind of matter
Matter
All matter takes up space. The amount of space an object takes up is the volume. All objects- specks of dust, schools, science books- have volume…. they cannot share the same space at the same time.
Matter and volume
The amount of space an object takes up is?
Volume
Liters and milliliters are the units most often used to express
Liquid volume
Graduated cylinders- used to measure the liquid volume when the measurement has to be accurate. The surface of a liquid in any container is curbed. To measure, you must look at the bottom of the meniscus
Measuring the volume of liquids
The curved surface of the liquid is called a meniscus
Meniscus
Volume is always expressed in cubic units. Cubic means having three dimensions: volume= length x height- we use this formula to calculate the volume of regularly shaped objects.
Volume of a regular shaped solid object
To determine the volume of an irregularly shaped object- measure the volume of water that the object displaces. Volume is NEVER expressed in liters or milliliters, always cubic units! To do this, you need to know that 1ml = 1 cubic cm, so the volume will be expressed in cubic units.

Mass is the amount of matter in an object. You and a peanut are both made up of matter- you are made up of more matter, therefore, you have more mass. The mass of an object is the same no matter where in the universe it is located. Mass is expressed in kilograms, grams, and milligrams
Matter and mass
A measure of the gravitational force exerted on an object
Weight
The more mass an object has, the greater the gravitational force on the object, and the greater the weight.
Difference between mass and weight
The tendency of an object to resist a change in motion.
Inertia
Is a measure of inertia
Mass
