The equation for linear motion can be understood in the context of the relationship between displacement, initial velocity, time, and acceleration. The chosen equation, which states that displacement (s) is equal to the initial velocity (u) multiplied by time (t) plus half of the acceleration (a) multiplied by the square of the time, encapsulates these relationships nicely.

This equation is derived from the fundamental principles of kinematics. It applies to objects moving with uniform acceleration and it allows us to calculate how far an object has traveled over a certain period when it starts with an initial velocity and is subjected to a constant acceleration.

The term (ut) represents the distance covered due solely to the initial velocity. The term (0.5at^2) accounts for the additional distance traveled due to the acceleration of the object over time. This combination captures the essence of simple linear motion under constant acceleration, making it a foundational equation in mechanics.

In contrast, the other answer choices represent different concepts. The equation involving (v = at + u) describes the final velocity after a time period and is another important kinematic relationship, while (F = ma) is Newton's second law relating force, mass, and
