Scientific meaning of velocity
WebFormally, the work done on a system by a constant force is defined to be the product of the component of the force in the direction of motion times the distance through which the force acts. For one-way motion in one dimension, this is expressed in equation form as size 12 {W= lline F rline left ("cos"θ right ) lline d rline } {} 7.1 WebVelocity is a vector expression of the displacement that an object or particle undergoes with respect to time .
