If Kofi hangs upside down by his knees from a horizontal bar at the park, what happens to the cap he is wearing and why? Make your response very short.
The cap Kofi is wearing will fall off his head because, when he inverts his position by hanging upside down, gravity will act on the cap in a direction away from his head towards the ground. Since there are no significant forces to hold the cap in place against the pull of gravity once it loses contact with his head, it will drop to the ground.
