What answers do you think your students would give to these "Simple" questions on force and motion? (Simple in quotes means tricky)

What is your acceleration right now? to within 1% of g.
What is your velocity right now?
What is the force of gravity on you right now?What is the net force on you right now? to within 1% of the force of gravity.
What are other forces on you right now?
Why doesn’t an electron fall into an atom?
(Why doesn’t the moon fall toward the earth?)
