Mass
What is the definition of mass?
The amount of matter in an object.
What is the definition of volume?
The amount of space an object takes up.
What is the definition of density?
The amount of matter in a given volume
orHow packed in an object is!
What is the definition of gravity?
It is a force that pulls on all matter.
What is matter?
Anything that takes up space and has weight!
A balance!
What is the formula we use to find the volume of a cube?
Length x Width x Height
How do you find the Density of an object? What's the formula?
Density equals Mass divided by Volume
What is the property that is used to measure the gravitational pull on an object?
Weight!
Name two units of measurement used to measure matter.
-Grams (g)
-Cubic Centimeters (cm3)
-Milliliters (mL)
-Newtons (N)
-g/cm3 or g/mL
How many grams are in 2.5 kilograms?
2500 grams!
What are the units of measurement we use for solid and liquid volumes?
Cubic centimeters (cm3) for solids and Milliliters (mL) for liquids
What are the units of measurement we use to label density, for both liquids and solids?
Liquids: g/mL
Solids: g/cm3
What tool do we use to measure weight? And what unit of measurement?
A spring scale is used to measure Newtons.
What is the definition of a physical property?
Anything about matter that we can measure.
What is the most accurate tool we have used to measure mass? Be specific.
A triple beam balance
What tool do we use to measure the volume of a liquid? A bonus 100 if you can say why its better than the other tool commonly used!
A graduated cylinder!
What is the density of water?
1 g/mL
State a difference between mass and weight!
-Mass is constant while weight is not.
-Mass is measured in grams while weight is measured in Newtons.
-Mass is measured with a balance while weight is measured with a spring scale.
What is force?
Any interaction on matter that effects its movement.
You have a cup of water and you want to measure the mass of only the water. What do you need to do first?
Measure the mass of the cup first!
You measure how much the level of water has risen when you slide an irregularly shaped object into the container of water. What is this method called?
Water Displacement
Red liquid: 1.47 g/mL
Blue liquid: .93 g/mL
White object: 1.03 g/cm3
In what order do these sink when dropped into a cup, from lowest to highest?
Red, White, and Blue
Murricaaaaa!
What two factors change the force of gravity?
The amount of mass and the distance between two objects.
Name every property that we have studied so far.
Mass, Volume, Density, and Weight.
