• True

• False

The arrows on a model of an electric field show where a ​ (a)   charge would "want" to travel if it could.

• positive
• negative
• neutral

NGSS.MS-PS2-5

Charged object A is ​ (a)   ​ because the arrows point ​ (b)   from the object.

• positive
• away
• negative
• toward

If the objects moved closer together, the energy in the field would ​ (a)   because ​ (b)   charges "want" to be together

• decrease
• opposite
• increase
• same

If the objects moved closer together, the energy in the field would ​​ (a)   because ​ (b)   charges do not "want" to be together and repel.

• opposite
• increase
• same
• decrease

If you wanted MORE energy in the field between these charged objects, bring them ​ (a)   because that would store more ​ (b)   in the ​ (c)   like the stretching of a string.

• further apart
• energy
• field
• closer together
• force
• charge

There is (a)   energy stored in the new distance. The two charges are ​ (b)   . The charges are ​ ​ (c)   .

• more
• repelling
• attracting
• unstable
• stable

NGSS.HS-PS3-5

There is (a)   energy stored in the original distance. The two charges are ​ (b)   . The charges are ​ ​ (c)   because they are further apart and the fields are not interacting.

• attracting
• unstable
• stable
• repelling
• less
