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?
Thank you for your reply. So, in the experiment what was measured and how was it measured?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.
You asked exactly the same question 3 weeks ago. Have you not found the answers satisfactory? Please don't re-tread old ground. If you have any follow-ups to make, make them in your other thread and show with your new questions that you've made an effort to absorb what you've already been told/shown.
