Physics in Theme Parks

Energy is defined in physics as the capacity or ability to do work. Life, food, and Disney are not scientific definitions for this concept.

Hydraulics is a branch of engineering that deals with the mechanical properties of liquids. These systems use pressurized fluid to transmit force to mechanical components.

Oxygen is the essential element required by human beings for cellular respiration. While nitrogen makes up the majority of the atmosphere, oxygen is the specific gas needed to breathe.

The Tower of Terror uses a cable system to pull the elevator car downward faster than the natural acceleration of gravity. Therefore, the statement that it falls at the rate of gravity is false.

Inertia is the tendency of an object to resist changes in its state of motion. When a roller coaster changes direction or speed, your body's inertia causes you to continue moving in your previous direction, making you slide in your seat.

The Tomorrowland Transit Authority PeopleMover uses linear induction motors, which are a type of electromagnetic propulsion, to move the vehicles along the track.

Potential energy is the energy stored in an object due to its position or configuration. In a roller coaster, the lift hill builds up gravitational potential energy that is later converted into kinetic energy.
