Step-by-Step Analysis

Let’s break down each option to determine whether it represents a force in physics. Option a: Strain. Strain is a measure of deformation in a material, not a force itself. It describes how much an object is stretched or compressed, but does not represent a push or pull. Option b: Normal Force. The normal force is the contact force exerted by a surface perpendicular to the surface. It is a classic example of a force and is indeed a force acting on objects. Option c: Displacement Force.
