Which scientific law can be stated as "Force = Mass x Acceleration"?

I taught these laws to 5th graders in Colorado. Even a ten year old can understand when explained in simple language. Fun experiments to illustrate the concepts too. P.S. I had a retired high school physical sciences teacher volunteering in my classroom who taught me how to make these concepts accessible to young people.

and in thermodynamics there is the Zeroeth law .. which makes the first law the second law. well it gets messy ..

Player #9398981, yeah pedantic hey . actually at school we always had the order as one three two .. like rule 2 ,equal opposite ,rule 3 f=ma .. turns out the schools text, curriculum renumbered them .. not thinking it broke history ...

Some one pushed me and I pushed him back... 3rd law! physics is amazing!
