Newton’s second
is all they know –
third law beckons
but they wont go
beyond the sum
of forces. Dumb!
Third’s on the test.

In response to Alex.
And for my students, who never seem to take a hint from “Newton’s third law is my favourite law…”. Perhaps I should set one of Alex’s poems as an exam question: “Identify and explain all references to Newton’s laws. Give your answer as either a sonnet or series of haiku.”
My favourite is the first, aka the Monday morning law…..
lol… yes, that’s a good term for it. And it’s very under-appreciated.
The name came from my Physics teacher at school. His example was the school pupil in bed, and the parent being the force that got them out of bed…..
Nice! I might use that.
what is newton’s second? first is “an object continues doing whatever it is currently doing unless an external force acts on it” and the third is “every action has an equal and opposite reaction” I think that’s right unless I’ve got those mixed up.
oh wait F=MA that was Force=Mass times Acceleration wasn’t it?
That’s the one 🙂
Or, better as a = F/m, as it’s the force that causes the acceleration, and 1/m is the constant of proportionality.
