The energy an object has due to its motion.

• A. Potential energy
• B. Electrical energy
• C. Thermal energy
• D. Kinetic energy

Answer: (D)

Energy an object has because it is moving is called kinetic energy. It depends on how heavy the object is and how fast it’s going, described by the formula 1/2 mv^2. Because the speed is squared, even small increases in velocity lead to larger increases in energy, and a moving object can transfer this energy to other forms when it slows down or hits something. The other terms refer to different kinds of energy: potential energy is energy due to position, thermal energy relates to temperature from microscopic motion, and electrical energy comes from electric charges or currents. So the description given matches kinetic energy.
