Energy stored within a system
Explication
Potential energy is defined as stored energy within a system, according to the source, and is ready to be converted into other forms.
Joule
Explication
The source states that the unit used to measure kinetic energy is the Joule (J), making it the correct answer. Calories, Watts, and Electronvolts are different units used for other measurements or contexts.
The energy associated with an object's motion
Explication
Kinetic energy is primarily associated with an object's motion, as indicated by its definition as energy related to motion.
Energy stored in objects that can deform and return to their original shape
Explication
Elastic potential energy is the energy stored in objects that can deform and return to their original shape, such as a mousetrap.
