Fan and attractor: forces from an extension

Theory

The fan pushes each body in its cone with $F=F_{max}(1-d/R)$. By Newton’s second law $a=F/m$, so light bodies accelerate more.

What to observe

• The foam ball flies far; the iron ball barely moves.
• The attractor bends trajectories like a planet’s gravity.
