Final answer:
The assertion regarding an object in motion possessing kinetic energy is correct, as kinetic energy is defined by the object's capability to do work due to its motion. Examples include a moving wrecking ball or a walking person.
Step-by-step explanation:
The assertion that an object in motion possesses energy, which is generally called kinetic energy, is a correct statement. Kinetic energy is the energy an object has due to its motion. This is exemplified by a wide range of scenarios, such as a speeding bullet, a walking person, or the movement of air molecules that produce heat. For instance, a wrecking ball in motion can do significant damage due to its kinetic energy. It's this capacity for doing work that defines kinetic energy.
The reason statement highlights the idea that kinetic energy is associated with moving objects because they can enact change or do work. This concept is fundamental when considering energy types. On the other hand, potential energy is the stored energy in an object due to its position, like a wrecking ball held high above the ground. If released, this potential energy converts to kinetic energy as the wrecking ball falls.
