\(\textit{Kinetic Energy}\) is the energy which a body possesses as a consequence of its motion, defined as one-half the product of its mass \(m\) and the square of its speed \(v\), \( \frac{1}{2} mv^{2} \). The kinetic energy per unit volume of a fluid parcel is the \( \frac{1}{2} p v^{2}\) , where \(p\) is the density and \(v\) the speed of the parcel. See potential energy. For relativistic speeds the kinetic energy is given by \(E_k = mc^2 - m_0 c^2\), where \(c\) is the velocity of light in a vacuum, \(m_0\) is the rest mass, and \(m\) is the moving mass. |
