Charge Check
Two objects have the same electric charge... what interaction do you predict?
Repulsion.
Explain the three results of our tape lab, and what that meant.
T-T repelled
B-B repelled
T-B attract
What is a scientific model used to do?
Explain and predict phenomena.
What is Ms. Bussler's dogs name?
Boots
The Sun is the closest example of what kind of astronomical object to earth?
a star
What are the three ways something can become charged?
Pull apart, rub/friction, contact with a neutral object
What charge is the VDG? How did we determine this?
We used a negative balloon (known charged object) and it repelled the VDG.
What are the three important aspects of a scientific model?
components
relationships
connection to phenomena
What is Ms. Bussler's dream vacation?
Iceland.
What force keeps the moon in orbit around the earth?
gravity
What makes a neutral object neutral?
Equal amounts of positive and negative charges...
Which element makes up most of the sun and stars?
hydrogen
What helps a negative balloon attract to a neutral wall? What characteristics does a neutral object have...
equal pos and neg...
charge shifts so pos attract to neg and vice versa
What three sports did Ms. Bussler play in high school?
golf, basketball, soccer
What animal has the highest blood pressure?
Hint: you find it in the zoo!
A giraffe
An object with an unknown charge attracts to a negative rod. What charges are possible and what additional test can be ran to make sure?
Positive/Neutral.
Hold to neutral object-- if nothing, neutral. If attracts positive.
Which metal is liquid at room temperatures?
mercury
Which way does an electric field face surrounding a positive object? Explain why.
Away.
Repels positive
Sushi
Name one of the two plants in our solar system that do not have moons...
Explain how car paint works...
The powder is the same charge, and repels each other. The car is the opposite charge, so it sticks!
A neutral pie pan touches the charged VDG then flies off. Explain the sequence using charge and force.
Charged THE SAME from contact and repels.
In an electric field model, what do we use? and what do they represent?
vectors, direction and magnitude.
What is Ms. Bussler doing on Nov 7?
Going to watch State lose!!!
What planet has the most moons???
Saturn
