+A **contact force** is any [Force](/wiki/force) that acts between two objects that are physically touching each other. These forces arise from direct physical interaction, such as pushing, pulling, or the resistive push of a surface, known as the [Normal Force](/wiki/normal_force). They manifest whenever matter directly interacts with other matter.
