Contact forces in chemistry form 3

Let's knock this out.

The term "contact forces" is primarily used in Physics to describe forces between objects that are physically touching, like friction or normal force.

In Chemistry, especially at Form 3 level, we focus on the interactions between atoms and molecules. These interactions are usually non-contact forces at the macroscopic level, such as:

• Electrostatic forces between charged particles (protons and electrons) within atoms, which form chemical bonds.
• Intermolecular forces (like Van der Waals forces or hydrogen bonds) that hold molecules together in liquids and solids. These are attractive or repulsive forces that act over very short distances but don't require physical "contact" in the same way a push or pull does.

So, while forces are fundamental to chemistry (e.g., holding molecules together), the specific term "contact forces" is not typically applied in a chemistry context.
