You take the newton meter and tell people to take e.g. sellotape and put it on the meter, they measure it write it on paper and they could do more examples (you can also just take anything and put it in a bag and then hang it on the newtons meter). You can also try to pull a drawer with it and explain to the people what they are just doing.
Its a matter of being scientifically rigorous. You can not claim the 2nd law as a law unless you first establish the first law.
the law of inertia
yeah.
Law of inertia.

Law of Inertia.
It isn't.
It is associated with the law of gravitational pull.
Actually, the first one is completely independent on the second one. But the second one doesn't make any sense without the first one.
Newtons first law of physics
Force.
It is sometimes referred to as the law of inertia.
