Answer:
C.the sum of the kinetic energy and the potential energy of an object
Step-by-step explanation:
This question can be viewed from two angles.
What is mechanical energy?
Mechanical energy is defined as the energy of an object in motion or the energy that is stored in objects according to their position.
Mechanical energy can also be defined algebraically as:
- Where U is the potential energy.
- Where K is the kinetic energy.
Answer Breakdown
- Choice C is the best answer because it covers both the equation for mechanical energy and the scientific definition. Kinetic energy is the energy of an object in motion while potential energy is the energy of a stationary object. When these energies are summed we can find the mechanical energy.
- Choice B is incorrect. The Energy associated with temperature is thermal energy. This energy can be endothermic or exothermic.
- Choice D is incorrect. The energy that is associated with electromagnetic radiation is based on the EM spectrum.
- Choice A is incorrect. The energy that is stored in chemical bonds is a type of potential energy but it is not mechanical. These bonds can be ionic, covalent, or metallic.
