Which of the following equations represents the position-time relationship?

Equation of motion: These are the mathematical equations used to find the final velocity, displacements, time, and so on of a moving object without taking into account the force acting on it.

These equations are only valid when the body's acceleration is constant and it moves in a straight line.

There are three types of motion equations:

v = u + at

2 a s = v² – u²

s = ut + ½ at²

Here, v = final velocity, u = initial velocity, s =  distance travelled by the body under motion, a = acceleration of body under motion, and t =  time taken by the body under motion.

From the above explanation, we can see that s = ut + ½ at²  represents the position-time relationship equation.
