Step-by-Step Analysis

Let’s break down what the question is asking: which items are forces, among the listed concepts. Option a: Displacement Force. In physics, displacement is a vector quantity describing a change in position; it is not a force itself. Therefore this option describes a quantity that is not a force, and the term as stated is not standard for a force. Option b: Static Friction Force. Friction in general is a contact force that resists relative motion between surfaces. Static friction is the force that prevents motion when objects are at rest relative to each other; since it is a contact force arising from interfacial interactions, it quali......Login to view full explanation
