Question

In a second law of motion it is mass X acceleration. It’s ability to apply a change in velocity on a given object

Answer 1

is directly proportional to the mass of the object and the acceleration it experiences. This means that an object with a greater mass will require a larger force to produce the same change in velocity as an object with a smaller mass. Similarly, an object with a greater acceleration will require a smaller force to produce the same change in velocity as an object with a smaller acceleration.
