A Box is against a walk a person pushes on the Box But the Box does not move is this situation an example of a force Yes this is an example of the force because gravity is pulling the Box down

No this is not an example of a force because a forces pulling an object

No this is not an example of a force because the Box did not move

Yes this is an example of a force because a force is a push or pull

Yes, this is an example of a force because a force is a push or pull.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.
