Here are the completed sentences for Aaron and Makayla:
a. Some objects have energy due to their positions above the ground. This is called potential energy. When an object gets higher above the ground, this kind of energy increases.
b. Some objects have energy due to their motion. This is called kinetic energy. When an object's speed gets faster, this kind of energy increases.
Now for question 2, identifying the type or types of energy for each situation:
c. Identify the type or types of energy described in each situation listed below.
-
One basketball is stored on a shelf about 4 feet high. Potential energy
-
One basketball is rolling on the floor. Kinetic energy
-
One basketball is falling through the hoop near the top of the basketball goal. Kinetic energy (It also has potential energy just before it starts to fall, but while it is falling, it is primarily exhibiting kinetic energy).
