Kinetic energy is a fundamental concept in physics that describes the energy an object possesses due to its motion.
To understand kinetic energy, consider an object with mass \( m \) moving with velocity \( v \). The kinetic energy \( KE \) of this object is given by the formula: \( KE = \frac{1}{2} m v^2 \).
This formula shows that kinetic energy depends on both the mass of the object and the square of its velocity, indicating that an increase in either mass or velocity will result in an increase in kinetic energy.
Kinetic energy is distinct from potential energy, which is the energy stored in an object due to its position or configuration, such as gravitational potential energy or elastic potential energy.
In the context of the given options, the correct description of kinetic energy is 'The energy an object possesses due to its motion.'
