Detailed Solution

This is because the energy of motion which has a movement of an object and particles are kinetic energy. Therefore the kinetic energy of mass in motion cannot be negative. So, it provides only magnitude and not the direction. Hence, kinetic energy is equal to half mass multiplied by velocity squared where velocity squared is always positive. Thus, the statement is true.
