Which term describes the relationship between the speed of an object and its energy level?

The relationship between the speed of an object and its energy level is described by the kinetic energy formula, which states that the kinetic energy of an object is proportional to the square of its speed. Specifically, kinetic energy (KE) is calculated as KE = 1/2 mv², where m is the mass of the object and v is its speed. This equation indicates that as an object's speed increases, its kinetic energy increases significantly due to the squaring of the speed term.

Therefore, the faster an object moves, the more kinetic energy it possesses. This relationship highlights the importance of speed in determining the energy an object has while in motion. In contrast, other options suggest incorrect relationships where speed decreases energy or has no effect, which do not align with the physical principles governing kinetic energy.
