An applied force refers to any external force exerted on an object by another object or person. It can cause changes in an object's motion or shape.
The net force is the vector sum of all forces acting on an object. It determines the overall effect on the object's motion.
The normal force is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface.
Tension Force: Tension force occurs when a string, rope, or cable is pulled at both ends. It transmits pulling forces along its length.
