What is the relationship between mass and kinetic energy?

The relationship between mass and kinetic energy can be described by the equation: Kinetic energy = 0.5 * mass * velocity^2. This equation shows that kinetic energy is directly proportional to mass, meaning that an object with a greater mass will have more kinetic energy as long as the velocity remains constant. This relationship is important in understanding the energy transformation that occurs in moving objects and is a key concept in the study of physics.
