WebApr 12, 2024 · The velocity of an object can be defined as the rate of change of speed with respect to the object’s position. In a simpler sense, velocity means the speed of an object in a specific direction. Velocity is a vector quantity as it requires both magnitude and direction to define it. The S.I. unit of velocity is m/s-1. WebUnlike velocity, acceleration, force, and momentum, the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy, the standard metric unit of measurement for kinetic energy is the Joule. As might be implied by the above equation, 1 Joule is equivalent to 1 kg* (m/s)^2. 1 Joule = 1 kg • m2/s2.
