IDENTIFYING VARIABLES For each testable question,
underline the independent variable. circle the dependent variable, and list 3 constant/control variables.

Independent Variable- One thing that the experimenter changes on purpose
Dependent Variable- Something that changes as a result of the independent variable

Constant/Control Variable - Something kept the same on purpose

answer would be letter choice (a),   a ball resting on a shelf. would be another example of potential energy   >   stored energy > not moving.

a ball spinning on a finger   >   kinetic energy > moving energy

a ball rolling on the ground   >   kinetic energy   > moving energy

a   ball flying through the air   > kinetic energy   >   moving energy
