* Size and Mass: Transformers are giant robots that can transform into vehicles. However, the physics of how they achieve this transformation, especially the rapid shrinking and expanding of their mass, is completely unrealistic.
* Gravity and Flight: Transformers can fly and hover in the air despite their enormous size and weight. In reality, they would require immense amounts of energy to counteract gravity and maintain flight.
* Speed and Impact: The Transformers move at incredible speeds and crash into things with seemingly no consequence. The forces involved in such collisions would be devastating, but the characters seem to experience minimal damage.
* Energy Sources: The source of the Transformers' power is never fully explained, but it seems to be an inexhaustible supply of energy that allows them to perform incredible feats.
* Sound in Space: The Transformers make loud noises even when they're in space, where there is no atmosphere for sound to travel through.
* Transformation Speed: The transformation process is often depicted as happening in a matter of seconds, which is impossible given the amount of mass that needs to be rearranged.
The Transformers franchise is primarily focused on action and entertainment rather than scientific accuracy. As such, many liberties are taken with physics, allowing for spectacular visual effects and exciting storylines.
So, while the Transformers movies are fun to watch, don't expect to see realistic physics at play.
