A wagon is traveling east with a frictional force of 30 N. It experiences a 60 N gravitational force pulling downward and counteracts that force with a 60 N normal force pushing upward. Look at the forces represented by the diagrams below. Calculate the unbalanced forces, and include the direction the object will move.

intermolecular forces are the forces between molecules or particles.

there are two kinds of van der waals forces: weak london dispersion forces and stronger dipole-dipole forces.

in molecule of water there are dipole-dipole forces between negatively charged oxygen from one molecule of water and positively charger hydrogen of another molecule of water.

hydrogen bond is an electrostatic attraction between two polar groups that occurs when a hydrogen atom (h), covalently bound to a highly electronegative atom such as flourine (f), oxygen (o) and nitrogen (n) atoms.
