For the helium balloon problem, I first do a related demo in class. It's a
pulley, cart, and hanging mass, and I attach a horizontal level to the
cart. When the mass is released, the cart accelerates to the right. Which
way does the bubble move? This is about inertia.
So the helium balloon question is similar.
For the ball thrown straight upward, I want the students to know that the
Earth's gravity is a constant 10 m/s2 downward.
For the ISS question, the spacecraft is accelerating so a force (due to
gravity) must be acting.
I don't deceive/trap my students
the questions I ask relate to what I am teaching.
I don't want physics to be scary and confusing
most textbooks already do this.
I will check out your "deceptive" questions
