Normal force
Definition
The normal force is the support force exerted by a surface to prevent an object from falling through it. It acts perpendicular to the surface and counterbalances the weight of the object.
Related terms
Weight: Weight is a measure of how heavy an object is and depends on its mass and acceleration due to gravity. The weight of an object is equal in magnitude but opposite in direction to its gravitational force.
Frictional force: Frictional force arises when two surfaces are in contact with each other and resist relative motion. It acts parallel or tangential to their interface.
Tension: Tension refers to a pulling force transmitted through a flexible connector, such as a rope or cable. It can be present in situations involving hanging objects or systems with ropes under tension.
