Students investigate changes in gravitational potential energy using paper clips, crumpled paper and shelves. They measure the masses of three paper clips and paper. They determine that the piece of paper has 3 times the mass of the three paper clips. They then place the objects on the floor, beneath the shelves. Determine the placement of the three paper clips and crumpled paper on the shelves so that both have equal gravitational potential energy.

One bar magnet sits on a table, and a rubber band suspends another magnet above it. In the view on the left, the upper magnet is held in place and cannot move. In the view on the right, the upper magnet has been released.
How did the potential energy change when the upper magnet was released? (SELECT ALL THAT APPLY)
Gravitational PE decreases
Elastic PE decreases
Magnetic PE decreases
Magnetic PE increases
Elastic PE increases
Two positive charges are held far apart within each other's force field. Which statements are TRUE? SELECT ALL THAT APPLY.
The charges will repel when released
The charges will attract when released
The charges have high PE before being released
The charges have low PE before being released
WHEN YOU DROP A TENNIS BALL FROM 3 METERS ABOVE THE EARTH’S SURFACE, WHAT HAPPENS TO THE GRAVITATIONAL POTENTIAL ENERGY AS THE TENNIS BALL FALLS?
PE decreases
PE increases
Two opposite charges are held far apart within each other's force field. Which statements are TRUE? SELECT ALL THAT APPLY.
The charges will repel when released
The charges will attract when released

Two positively charged particles are attached to springs that are capable of stretching and compressing. A metal sphere is placed near each charged particle, as shown in the diagram.
A positive charge is slowly added to Sphere A. An equal amount of negative charge is slowly added to Sphere B. Assume that the two systems are isolated from each other.
How does the elastic potential energy change for each spring?
Both springs increase in PE
Spring A increases; Spring B decreases
Spring A decreases; Spring B increases
Both springs decrease in PE
