Which description best defines kinetic energy?

• A. Energy stored due to position.
• B. Energy transferred as motion without considering motion.
• C. Energy of motion.
• D. Energy stored in chemical bonds.

Answer: (C)

Kinetic energy is the energy an object has because it is moving. It depends on both how heavy the object is and how fast it’s going, and it increases with speed (in fact, it grows with the square of velocity). The formula KE = 1/2 m v^2 captures this idea: more mass or higher speed means more kinetic energy. This is why a moving car or a flying baseball carries significant energy that can be transferred or transformed when it slows down or collides. This description matches the idea of energy of motion, distinguishing it from energy stored due to position (potential energy) or energy stored in chemical bonds (chemical energy).
