How is kinetic energy defined?

• A. Kinetic energy is the energy of an object due to its heat
• B. Kinetic energy is the energy of an object due to its motion
• C. Kinetic energy is the energy stored within an object
• D. Kinetic energy is independent of velocity

Answer: (B)

Kinetic energy is specifically defined as the energy possessed by an object due to its motion. This definition emphasizes the relationship between the energy and the velocity of the object. Mathematically, kinetic energy (KE) is expressed as \( \frac{1}{2}mv^2 \), where \( m \) is the mass of the object and \( v \) is its velocity. This formula illustrates that the kinetic energy increases with the square of the velocity, indicating how much the motion of the object contributes to its energy. In essence, the faster an object moves, or the greater its mass, the more kinetic energy it holds. Understanding kinetic energy in this way helps differentiate it from other forms of energy, such as thermal energy or potential energy, which relate to temperature or position, respectively.

Mathematically, kinetic energy (KE) is expressed as ( \frac{1}{2}mv^2 ), where ( m ) is the mass of the object and ( v ) is its velocity. This formula illustrates that the kinetic energy increases with the square of the velocity, indicating how much the motion of the object contributes to its energy.
