If a rock were taken from earth to the moon, how would its mass and weight be affected?
|
Rock will weigh less because there is no gravity on the moon. The force of the gravity between your body and the moon would be less.
|
|
List four properties of matter
|
liquid, gas, solid and magnetism
|
|
What is magnetic another property of?
|
Matter
|
|
What happens when an object is placed in water?
|
If the upward push is strong enough compared to the object's weight, the object will float.
|
|
How do you measure weight?
|
Use a quantity called the newton to measure force. One newton is the same of .22 pounds
|
|
How is volume measured?
|
Cubic centimeters
|
|
What happens if the density is more than the water's density?
|
The matter will sink.
|
|
What happens if the density is less than water's density?
|
The material will float.
|
|
What is buoyancy?
|
The push up on an object
|
|
What is density?
|
How tightly packed matter is.
|
|
What are three forms of matter?
|
Gas, Liquid and solid
|
|
What is actually the force of gravity between Earth and a book?
|
Weight
|
|
Measures how much space a sample of matter takes up
|
VOLUME
|
|
What does Conduct do?
|
It allows heat or electricity to flow through readily
|
|
What properties are used to classify matter?
|
density, ability to conduct electricity and magnetism
|
|
What metal is a good conductor of electricity?
|
Copper
|
|
What is Density?
|
A measure of how tightly packed matter is; the amount of mass contained in a given volume
|
|
What is volume
|
The amountof space an object takes up
|
|
What is weight?
|
(on Earth) a measure of the force of gravity between Earth and an object
|
|
What is Mass
|
The amount of matter in an object
|
|
Why is plastic used to coat the wire that conducts electricity?
|
It insulates the passage of the electricity so the person holding the wire will not get shocked.
|
|
What is buoyancy?
|
The upward push on an object by the liquid (or gas) the object is placed in
|
|
How many poles does a magnet have?
|
2 -North and South
|
|
How do engineers and scientists use properties of matter?
|
When they design and build things
|
|
How is mass measured?
|
Kilograms
|
|
What does Insulate mean?
|
It does not allow heat or electricity to flow through readily.
|
|
What is magnetic?
|
when certain object push or pull on each other.
|
|
Anything that has mass and takes up space
|
MATTER
