I believe the answer is "radioactive decay".
Explanation:
If the displacement of an object is proportional to the square of the time taken then the body is moving with uniformly accelerated motion as it will follow Newton's second equation of motion for a particular initial velocity, which can be given by, s=ut+21at2.
hope this is helpful to you
