Answer:
Baseball: PE
Satellite: KE
Sky Diver: KE
Basketball: PE
Arrow: KE
Cliff Diver: PE
Swinging Girl: PE
Grasshopper: PE
Bobsled: KE
Slingshot: PE
Explanation:
For a thrown object, KE and PE are in a sort of equilibrium. As the object climbs towards its highest point, it slows down as the initial KE that initiated the movement runs out. At the highest point, it is out of kinetic energy and full of potential energy. Gravity then pulls on the object and causes it to accelerate, thus giving it more KE. The PE at the top of the arc is because at that point, the object has the potential to fall to earth. This is the reasoning behind the baseball, swinging girl, and grasshopper.
This is, in a way, the same reasoning behind the other potential energy cases as well. The basketball, cliff diver, and slingshot are all about to start moving. The first two will be pulled by gravity and the last one will be propelled be the stretchy slingshot material attempting to snap back into place.
All of the KE examples are due to the object or person actively moving towards or around something. This means that they have kinetic energy--the energy of movement!
