Newton's second law states that an unbalanced force will cause an object to accelerate according to the following equation, F=mxa
where F is the force, m is the mass of the object, and a is the acceleration that results. This equation is a theoretical model that can predict how objects will move.
Lewis plans to push a five kilogram ball with a different force for five trials. Which graph below predicts a pattern of motion for the ball that matches the theoretical model?

A. Y
B. Z
C. W
D. X​
