What is Newton's 3rd Law?
Hint: Think of a rocket ship!
The Law of Action-Reaction: Every action has an equal and opposite reaction
How are speed, velocity, and acceleration related?
Possible answers:
They all have a component of speed - they all have to do with motion
They all have distance and time units
