Solution
Answer to the Question
The term that describes the energy of motion is:
A. Kinetic energy
Explanation
Kinetic energy is the energy that an object possesses due to its motion. The formula for kinetic energy () is given by:
where is the mass of the object and is its velocity.
In contrast, the other options refer to different forms of energy:
- B. Elastic energy refers to potential energy stored in elastic materials as the result of their stretching or compressing.
- C. Electrical energy is the energy derived from electric potential energy or kinetic energy of charged particles.
- D. Gravitational potential energy is the energy an object possesses because of its position in a gravitational field, commonly associated with its height above the ground.
Thus, the correct answer to the question is indeed A. Kinetic energy.
