I How was F = ma obtained?

How was F = ma obtained? What is mass? If you say mass is amount of matter, then what is matter? How did they measure accelerations at that time?

Your first question requires the second. Typically, mass is defined as "resistance to a change in motion": the more force require for acceleration then greater the mass: m= f/a from which f= ma immediately follows.

Thank you for your reply. So, in the experiment what was measured and how was it measured?
