According to Newton's second law of motion, force is equal to mass times acceleration

Yes. Right you are. Truer words were never spoken.

If you want to get historically technical about it, he actually wrote that

force is equal to the time rate of change of momentum. But that's exactly

the same as (mass) x (acceleration), which is the way almost everybody

uses it today, and the way it's taught.

So, again, you've got it right, and your "question" is a true statement.

Now, do you have an actual question to ask?
