In "Wile E. Coyote Experiments With Energy ZAP" by Suzanne Slade, Wile E. Coyote's ACME Flyer transforms energy into different forms, primarily kinetic energy (the energy of motion) and potential energy.
However, the ACME Flyer is not 100% energy efficient. This is typically due to energy losses that occur in any real-world system, such as friction, air resistance, heat loss, and other forms of energy dissipation. These losses prevent the system from converting all input energy into usable output energy, making it impossible to achieve 100% efficiency.
