* Contact Forces: These are the forces that require direct physical contact. Think of pushing a box, kicking a ball, or friction between your hands rubbing together.
* Examples: Normal force, friction, applied force, tension, spring force.
* Non-Contact Forces: These forces act on objects even when they are not touching.
* Examples: Gravity, magnetism, electrostatic force.
So, while many forces we experience in everyday life require contact, forces like gravity and magnetism can act from a distance.
