Electric charge is neither created nor destroyed, but can be transferred back and forth between objects.
true
false
Two students are trying to decide whether or not Object A is charged. They perform the following two tests:
Test 1: They bring Object A near a positively charged tape and observe repulsion.
Test 2: They bring Object A near a negatively charged tape and observe attraction.
These two tests lead to the conclusion that Object A is _____.
charged negatively
charged positively
electrically neutral
charged, but with an unknown type of charge
This model of the balloon shows ______ positive charges than negative charges. So this balloon is _____ charged.
fewer/positively
more/positively
fewer/negatively
more/negatively
Which of the following will NOT change in different gravitational fields?
Electric field lines go OUT of (a) charge, and INTO (b) charge.
Which diagram correctly shows the electric field around a POSITIVE charge?
A
B
Which diagram correctly shows the ATTRACTION between 2 OPPOSITE charges?
A
B
Both
Neither
Which diagram correctly shows the REPULSION between between 2 IDENTICAL/LIKE charges?

The Electric Field gets STRONGER when the distance is (a) , and WEAKER when the distance is (b) .
What happens to the force between two charged objects when you DOUBLE (2x) the distance between them?
2X
1/2X
4X
1/4X
As distance between two objects INCREASE the pull of gravity will __________.
Increases
Decreases
Stays the same
What would be the difference in your weight if you were 5x farther from the center of the earth than you are now?
1/5
1/10

Drag and drop the inverse square fractions to their correct place at different distances from the source
1
1/4
1/9
According to Inverse Square Law, the strength of the gravitational/electricity fields will get (a) when distance is increased. For example, if the distance is doubled or increased by 2x, the field will get weaker by (b) . If the distance is increased by 3x, then the field will get weaker by (c) .
As the distance from the source increases, will the field strength ever reaches 0 (zero)? Hint: the x axis is an asymptote)
Yes! There will be a distance where gravity or electricity will be 0
No! The field will get weaker and weaker but will never disappear.
