What is kinetic energy?

• A. Energy of Motion
• B. Energy Based on Position
• C. Energy Stored in Chemical Bonds
• D. Energy to Push a Fluid

Answer: (A)

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 moving, with the relationship shown by KE = 1/2 m v^2. Because velocity is squared, doubling the speed has a bigger effect than doubling the mass. This distinguishes kinetic energy from other energy types: potential energy is energy of position, chemical energy is stored in chemical bonds, and energy related to pushing a fluid describes work done to move fluid rather than a basic energy form. So the energy of motion best captures what kinetic energy means.
