1. Two balloons are given an electrostatic charge by rubbing them with a wool cloth. Which observation provides evidence of the force that the balloons exert on each other over a distance because of their charge?
C
Name three types of Potential Energy and give examples of each.
Gravitational - a rollercoaster at the top of a ramp
Static - static electricity (before you shock someone)
Chemical - a battery
Elastic - a spring
The rubber band and bouncy ball experiments best demonstrated what point that we wrote a CER about?
the position of an object affects the amount of potential energy the object possesses
What are the 2 brain facts we went over at the start of the unit?
1. The more times you review/do something, the better you get/the more you remember it
2. Your brain has plasticity, but if you label you limit.
Students build an electrostatic charge on the surface of two balloons by rubbing them with wool cloth. Pacing the balloons close to each other creates a system with potential energy. The potential energy in this system is a result of the fact that the balloons -
B
How does playing a pinball machine demonstrate three forms of potential energy?
Spring potential in the moment before launching the ball. Chemical potential in the player's ability to turn their lunch into energy to play the game. Gravitational- when the ball is at the top of ramps.
What kind of potential energy did the rubber band and bouncy ball experiment explicitly show?
Gravitational potential energy and elastic potential energy?
What did the "brain throwing" activity show us about how our brain works?
It showed that our brain is adaptable.
