WebThis equation says that a net force of zero implies that the velocity v → v → of the object is constant. (The word “constant” can indicate zero velocity.) Newton’s first law is … WebIf the starting time t_0 t0 is taken to be zero, then the average velocity is written as below: v_ {avg}=\dfrac {\Delta x} {t} vavg = tΔx Note: t t is shorthand for \Delta t Δt. Notice that this definition indicates that velocity is a vector because displacement is a vector. It has both magnitude and direction.
