The clue is in the question.
Isaac Newton, he discovered: -Newton's First Law of motion. -Newton's Second Law of motion. -Newton's Third Law of motion.
F = m a
yea
His First Law and Second Law both do.
Mass
newtons third law of motion
This is because two concepts are derived from the newtons second law. First : Force . F = m * a Second : momentum .. p = m * v
Newton's second law of motion.
