Answer:- <em>If speed of a body increases or decreases then the kinetic energy of body increases or decreases vice-versa.</em>
Step-to-step-explanation:-
The kinetic energy and square of speed are directly proportional.
The formula of kinetic energy is given by :-
,where v is the speed of the object.
Since both are directly proportional, therefore the hypothesis that would illustrate the relationship between speed and kinetic energy is given by :-
"<em> If speed of a body increases or decreases then the kinetic energy of body increases or decreases vice-versa."</em>
