Question

during the tennis ball drop demonstration, a pan was hit from underneath the tennis ball with great force. instead of flying forward along with the pan, the tennis ball dropped into the cup below. why is that? (pictured below is an egg instead of a tennis ball) hitting the pan creates an upwards force on the egg that allows it to defy the force of my hand on the pan the egg can momentarily ignore gravitational force because of the impact on the pan the egg is not attached to the pan or the toilet paper roll, so when the pan is hit by my hand, there is no force applied to the egg besides the force of gravity

Explanation:

La pelota de tenis (o el huevo en la imagen) no está unida al recipiente. Cuando se golpea el recipiente desde debajo, no hay fuerza aplicada a la pelota de tenis excepto la fuerza de gravedad, lo que hace que caiga hacia abajo en el vaso.

Answer:

The egg is not attached to the pan or the toilet paper roll, so when the pan is hit by my hand, there is no force applied to the egg besides the force of gravity
