====== Newton's Second Law======

===== Prompt =====

** "Write down Newton's second law." **

===== Context =====

This [[strategy:smallwhiteboard:|SWBQ]] follows up on the [[courses:activities:cfact:cfsurvivor|Survivor in Space]] activity and is used as a segue into generalizing Newtons's second law to systems of many particles. 

===== Wrap Up =====
Collect several student responses. Many students will respond with an introductory form
$$F = m a$$
but be sure to collect boards that remind students that Newton's second law is an equality between vector quantities. If no students bring up the second-derivative nature of the acceleration [!FIXME more]. 

This SWBQ is intended to connect directly to a derivation of [[courses:lecture:cflec:cflecreducedmass|reduced mass]].
