With an electric garage door opener/closer, there are systems to prevent the door from closing on a child who might be in the way. If the infrared sensor across the door is blocked by a leaf or any other object, the door will close and open immediately, or not close at all. If there is a rock or other object that is pushing against the door as it tries to finish closing, the door will immediately open. Sometimes a moth may construct a cocoon in the sensor, blocking the IR and producing similar results.

Why do balls bounce?
Balls bounce because of the conservation of energy. When the ball is pressed down, energy is stored in it due to compression. Upon release, this stored energy is transferred into kinetic energy, causing the ball to spring back up.
