Newton's first law is to define force
Second law to measure force
Third law to know about nature of force
What about fourth law? I have not heard about it.
May be your expectation with gravitation
Isaac Newton, he discovered: -Newton's First Law of motion. -Newton's Second Law of motion. -Newton's Third Law of motion.
His First Law and Second Law both do.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
acceleration
This is because two concepts are derived from the newtons second law. First : Force . F = m * a Second : momentum .. p = m * v
The clue is in the question.
Newton's second law of motion is when an object meets force it will accelerate.
the law of inertia
The law of inertia (it relates to an object's resistance to the change in motion)
yea
F = m a
Newton's third law of motion is that for every action there is an equal and opposite reaction. This law is also called reciprocal motion/force or "action-reaction."
