Answer:
Velocity
Explanation:
"The principle is that the slope of the line on a position-time graph is equal to the velocity of the object. If the object is moving with a velocity of +4 m/s, then the slope of the line will be +4 m/s."

Answer:
non linear square relationship
Explanation:
formula for centripetal force is given as 
a = mv^2/r 
here a ic centripetal acceleration , m is mass of body moving in circle of radius r and v is velocity of body . If m ,and r are constant we have 
a = constant × v^2
a α v^2 
hence non linear square relationship
