The given sentence best describes: b. Newton's second law, the law of acceleration.
Newton's Second Law of Motion is also referred to as the law of acceleration and it states that the acceleration of an object or body is directly proportional to the force acting on the object or body and inversely proportional to its mass.
Mathematically, Newton's Second Law of Motion is given by the formula;
[tex]Acceleration = \frac{Force}{Mass}[/tex]
In this scenario, as a result of the mass possessed by the iron man on the left, it took more force to accelerate him than it took to accelerate the iron man on the right. Hence, the above best describes Newton's Second Law of Motion, which is also referred to as the law of acceleration.
