Final answer:
The equation for the position-time relation for an object with constant acceleration is s = ut + 1/2at^2.
Step-by-step explanation:
The equation for the position-time relation for an object moving with constant acceleration can be derived using the graphical method. The equation is s = ut + 1/2at^2, where s is the position, u is the initial velocity, a is the acceleration, and t is the time. This equation represents the position of the object at any given time when it is experiencing constant acceleration.
