Document Summary
250911289: if a collision occurred with someone who weighed twice as much as your relative magnitude would decelerate twice as much. The magnitude of acceleration is affected by mass, because the person colliding into you weighs twice as much, you would both experience an opposing force but their force would have a greater impact. Thus, making you decelerate twice as much than the person that weighs more: the mass of your arm is what makes up the arm and its inertia. Inertia as newton"s first law dictates is that objects don"t like to be accelerated due to inertia they possess. The mass of your arm is related to inertia as is acts to prevent linear acceleration. Mass moment of inertia differs from mass of your arm as it shows resistance against being angularly accelerated. Angularly accelerated is also known as rotational inertia.
