Greater velocity
Webv = final velocity, u = initial velocity, a = acceleration, and Δs denotes change in displacement ΔK = maΔs, so from equation (1) ΔK = m (v^2 - u^2) / 2 => ½ mv^2 - ½ mu^2 but If kinetic energy is the energy of motion … WebIf an object changes direction in its journey, then the average speed will be greater than the magnitude of the average velocity. Speed is a scalar, and average velocity is a vector. Average velocity indicates direction and can be represented as a negative number when the displacement is in the negative direction.
