Test For Unit – Grade 7 Page 4 A hyper loop is a proposed mode of passenger and/or frieght transportation. A hyper loop is a sealed tube or system of tubes through which a pod my travel free of air resistance or friction conveying people or objects at high speed while being very efficient. A dual-mode vehicles is a vehicle that can run on conventional road surfaces or a dedicated track know as a guide way. Dual-mode vehicles are commonly electrically powered and run in dual- mode for power too, using batteries for short distances and low speeds, and track-fed power for longer distances and higher speeds.
