Repulsive: North and north, south and south
How do we find VOLUME of a regular shaped object?
How do we find VOLUME of an irregular shaped object?
Regular: Length X Width X Height
Irregular: Water Displacement, 1st#-2nd#=Volume
Weight is the measure of the force of __________ on an object
Gravity

What is Atoms packed closely together and vibrate in place?
Solid
A sample of iron has dimensions of 2cmX3cmX2cm. If the mass of this object is 94g. What is the density?
D=7.83
Mass: 94g
Volume: 2X3X2=12
94/12=7.83
Does an astronaut have more mass on earth than in space? Why or why not?
No, because they would have the same amount of matter.
The amount of space something takes up
Volume
What's the difference between an insulator and conductor?
Insulator= Prevents electricity to flow
Conductor= Allows electricity to flow
What are 5 different physical properties of matter?
Mass, Volume, Density, Conservation of mass, Hardness, Luster, Malleability, Solubility, Melting point, Electrical conductivity, Freezing point, Boiling point.
An irregular shaped stone was lowered into a graduated cylinder holding 2.0ml. The height of the water rose to 7.0ml. If the mass of the stone was 25g, what is the density?
D= 5
Mass: 25g
Volume: 7-2= 5ml
25/5= 5
Which action will change an object’s weight, but not its mass
