A ball is dropped from a height of 20 ft into a trampoline. When it hits the trampoline it produces a 2-foot depression in the trampoline before bouncing back to a maximum 10 feet Identify two transformations of energy occurring during this process and and then describe the evidence that confirms that each transformation confirmed edulastic

gravity causes stares to cluster i think so

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.
