If the net work done on an object is zero, then the object's kinetic energy will remain the same. This is because work done on an object is directly related to the change in kinetic energy of the object, as stated by the work-energy theorem: Wnet = ΔKE. If Wnet is zero, then the change in kinetic energy (ΔKE) is zero as well, which means the kinetic energy of the object remains the same.
