Which of the following is the best description of movement between an uncharged balloon and beads?
No motion observed.
Some beads moved toward the balloon and some moved away from the balloon.
Which of the following is the best description of movement between a charged balloon and beads?
No motion observed.
Some beads moved toward the balloon and some moved away from the balloon.
The best explanation for the motion of the beads with a negatively charges balloon is ___.
PICK TWO!
none of the beads have a charge
some beads have a positive charge
some beads have a negative charge
the negative charge of the balloon goes away
Why would some beads be repelled?
The balloon is negatively charged and some beads are negatively charged
The balloon is negatively charged and some beads are positively charged.
Why would some beads be attracted to the balloon?
The balloon is negatively charged and some beads are negatively charged
The balloon is negatively charged and some beads are positively charged.
How did the balloon get a negative charge?
rubbing with a damp cloth
rubbing with a wool cloth
<Use poster A/B>
How does position affect energy transfer to the objects in system A/B?
Pick TWO!
When two like charged objects are closely positioned, potential energy increases.
When two like charged objects are closely positioned, potential energy decreases.
When the distance between two like charged objects increases, potential energy increases.
When the distance between two like charged objects increases, potential energy decreases.
<Use poster A/B>
Which motion must happen for potential energy to be released in system A/B?
The objects must be attracted to each other.
The objects must be repelled from each other.
What is the mechanism for that release in this system?
Gravitational force of repulsion
Electric force of repulsion
Gravitational force of attraction
Electric force of attraction

<Use posters A/B and C/D>
Which set of diagrams would be most similar to representing interacting objects that exert force in a gravitational field system?
A/B
C/D
<Use posters A/B and C/D>
Could diagrams A/B and C/D be used to represent interacting objects that exert force in a magnetic field system?
Yes, if negative and positive charges are substituted for north and south poles.
No
