“Powered” is an adjective used to describe something that is operated, energized, or driven by a source of power. This power can be derived from various energy forms such as electricity, fuel, human effort, or other sources, enabling the object or system to perform specific functions or tasks.
Examples:
- Electrically Powered Devices:
- Example: “Many modern gadgets, such as smartphones and laptops, are powered by rechargeable batteries.”
- Fuel-Powered Vehicles:
- Example: “Cars, motorcycles, and airplanes are examples of vehicles powered by internal combustion engines fueled by gasoline or diesel.”
- Human-Powered Transportation:
- Example: “Bicycles and manual scooters are examples of human-powered transportation, relying on physical effort for propulsion.”
- Solar-Powered Technologies:
- Example: “Solar-powered calculators, street lights, and panels generate electricity using sunlight as the energy source.”
- Wind-Powered Energy:
- Example: “Wind turbines are structures with large blades that convert wind energy into electricity, providing a source of clean, wind-powered power.”
- Battery-Powered Appliances:
- Example: “Cordless drills, flashlights, and remote controls are examples of household appliances that are powered by batteries.”
- Hydroelectric Power:
- Example: “Hydroelectric dams harness the power of flowing water to generate electricity, providing a sustainable and renewable source of power.”
- Nuclear-Powered Facilities:
- Example: “Nuclear power plants generate electricity through controlled nuclear reactions, providing a significant source of power for communities.”
- Steam-Powered Machinery:
- Example: “Historically, steam engines powered locomotives, ships, and factories by converting the energy from steam into mechanical work.”
- Muscle-Powered Exercise Equipment:
- Example: “Stationary bikes, treadmills, and rowing machines are commonly found in gyms and are powered by the physical effort of the user.”
- Diesel-Powered Generators:
- Example: “In remote areas or during power outages, diesel generators can be used to produce electricity and power essential appliances.”
- Rocket Propulsion:
- Example: “Spacecraft are often powered by rocket engines that use fuel combustion to generate thrust, allowing them to travel through space.”
- Geothermal Power:
- Example: “Geothermal power plants tap into the Earth’s internal heat to produce steam, which is then used to generate electricity.”
- Pedal-Powered Vehicles:
- Example: “Pedal-powered vehicles, such as pedal cars and pedal boats, rely on the pedaling motion of the user for propulsion.”
- Gas-Powered Tools:
- Example: “Lawnmowers, chainsaws, and leaf blowers are examples of tools that are often powered by gasoline engines for outdoor maintenance.”
- Magnetic Levitation (Maglev) Trains:
- Example: “Maglev trains use electromagnetic propulsion to levitate above the tracks and are powered by electricity, allowing for high-speed transportation.”
- Biofuel-Powered Engines:
- Example: “Some vehicles and machinery can be powered by biofuels, which are derived from renewable sources such as plant oils or animal fats.”
- Hand-Cranked Devices:
- Example: “Emergency radios or flashlights often come equipped with hand cranks, allowing users to generate power manually when needed.”
