WONDER #2433: How Does Electromagnetic Propulsion Work?
Question 1 of 3
What is electromagnetic propulsion?
- The use of fossil fuels to make cars move.
- The force that gives gravity its strength.
- The law of physics that lets spaceships take off.
- The use of electromagnetism to make objects move forward.
Question 2 of 3
Which piece of evidence shows that using lighter fuel would greatly reduce the weight of space ships?
- “For example, NASA’s Space Shuttles had a liftoff weight of 4.5 million pounds”
- “If the EmDrive does work, it would be a much cleaner method of space travel.”
- “In the case of the Space Shuttles, fuel made up about half the weight of the entire craft at liftoff.”
- “Many scientists chalk the EmDrive up to pseudoscience. They think it defies Newton’s Third Law.”
