"WebNewton's first law says that if the net force on an object is zero ( \Sigma F=0 ΣF = 0 ), then that object will have zero acceleration. That doesn't necessarily mean the object is at rest, but it means that the velocity is constant. In other words, constant zero velocity—at rest—or constant non-zero velocity—moving with a constant velocity. " - Moseley's law equation
