Genre: Science Fiction
Based off a novel, Arthur C. Clarke
Four major sections

Jupiter and Beyond the Infinite
Centripetal Motion: movement of an object along the circumference of a circle or rotation along a circular path
Unlike many other science fiction movies, 2001: A Space Odyssey contains widely accurate portrayals of space.
Kubrick's work operates almost completely inside a movie-universe of realistic physics.
The special effects are also extremely well done for the time of its creation.
The Physics of 2001
The part of the ship that employs uniform circular motion is large and circular.
Uniform Circular Motion
Silence in Space
Whereas light can move through a space that is void of any sort of matter, sound is moves from point A to point B by vibrating the particles of whatever medium that it is traveling through.
When an object follows a circular path, there must always be a force present pulling the object towards the center or else it would just continue in a straight line.
This acts as a normal force.
On earth, the force of gravity that we feel is actually just the normal force of the earth pushing back against our weight.
If the proper normal force is acting on the human body, this feeling can be simulated causing a sensation of “artificial” gravity.
Typical Response to: Artificial Gravity
Even ignore concept altogether
ex. Star Trek
ex. Star Wars
Typical Response to: Sound in Space
Add sound effects of weapons and engines
Tie Fighters in Star Wars
Unlike on earth, where we usually hear sound via the vibration of air or water particles, space is mostly void of matter, leaving no way for sound to even leave its source.
The characters walking around seem to be experiencing the same force of gravity that they would on earth.
Due to its size, the force of gravity on the moon is about 6.1 times less on the moon than on earth. This means that the average man weighing 70kg on earth would only weigh 11.6kg on the moon.
If 2001 portrayed this correctly, the serious tone of the group of astronauts walking towards the obelisk would have been replaced with the silliness of several trained professionals bouncing around trying to keep their footing.
The method is used, but it is applied to a spacecraft far too small for any real success
Typical Response to: Uniform Circular Motion
Uniform circular motion: the motion of a body traveling a circular path at constant speed. The distance of the body from the axis of rotation and its velocity are both constant at all times, but the velocity is not. The changing velocity indicates an acceleration, which is produced by a centripetal force.
Newton's Third Law
When one body exerts a force on a second body, the second body simultaneously exerts a force equal in magnitude and opposite in direction on the first body.
When the door, Dave, and the air were expelled out the back of the pod, the pod should have gone flying in the opposite direction in space, but did not. It is unlikely thrusters would have been strong enough to counteract the force.
