van der Waal's force An attractive force existing between atoms and molecules of all substances. The force arises as a result of electrons in neighboring atoms or molecules moving in sympathy with each other. This force is responsible for the term a/v2 in van der Waal's equation of state. In many substances this force is small compared with other interatomic attractive and repulsive forces present.
