The celestial object that appears to move backwards among the stars is a planet in retrograde motion. This happens when a faster-moving planet "laps" a slower-moving outer planet from the viewpoint of Earth, causing it to look like it is moving backwards relative to the fixed stars in the sky.
Astronauts' poop is sealed in bags on the International Space Station and stored until it is trashed in a spacecraft or cargo vehicle that burns up upon re-entry into Earth's atmosphere. Some missions have experimented with recycling waste into useful resources.
The conservation of momentum is such that, when a rocket throws fuel and gas out of its thrusters, in order to maintain equilibrium, the rocket moves forwards to counter the motion backwards of the propellant.
The Canadarm is a robotic arm used on the Space Shuttle and the International Space Station. It is used to manipulate payloads, support astronauts during spacewalks, and assist in spacecraft docking and undocking operations. The Canadarm plays a crucial role in assembling and maintaining spacecraft in orbit.
Michael Jackson is credited with popularizing the moonwalk, a dance move where the dancer moves backward while appearing to be walking forwards. While Jackson did not invent the moonwalk, he helped popularize it during a performance of "Billie Jean" on the television special "Motown 25: Yesterday, Today, Forever" in 1983.
The atoms of the particular medium in which the sound is produced moves backward and forwards in sound.
A swing!
When sound moves forwards and backwards rapidly, it is called oscillation. This back-and-forth movement is what creates sound waves.
The truck is heavier
no bird can only move backwards! only a hummingbird has the ability to move backwards but it also moves forwards and left to right!
Is this a serious question? Cuz' lots of things do. :p
When you add integers, you generally move forwards on the number line if you are adding positive integers and backwards if you are adding negative integers. For example, adding 3 to 5 moves you forward to 8, while adding -2 to 5 moves you backward to 3. The direction depends on the signs of the integers involved.
The tympanic membrane, or ear drum. A thin piece of skin inside the ear that moves backwards and forwards when sound waves reach it
The eardrum (tympanic membrane) moves backward and forward in response to sound waves, which then causes the tiny bones in the middle ear to vibrate and transmit the sound to the inner ear.
A door! :)

Narrative continuity is when the story (narrative) moves from one point in time to another sequentially. IE--the story does not jump forwards and backwards in time, as in Chuck Palahniuk's Invisible Monsters, for example.
