If the same strength force is exerted on two objects why might they be affected differently?

Due to their mass

Explanation:

If the same strength force is exerted on two objects they might be affected differently due to their mass.

The way objects reacts to a force impact is largely dependent on their mass.

The mass of an object is the amount of matter it contains.

According to the Newton's second law of motion, the force applied on a body is directly proportional to the product of its mass and acceleration.

       Force  = mass x acceleration

Therefore, the way a force acts on a body is a function of its mass.

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
