If you have a mass of 50 kg on Earth, what is your weight in newtons? An object with more mass is pulled by gravity with greater force. Mass and weight are closely related. However, the weight of an object can change if the force of gravity changes. On Earth, the force of gravity is the same everywhere. So how does the force of gravity change? It doesnt if you stay on Earth. What if we travel to another planet or moon in our solar system? Look at the photo of astronaut Edwin E. Aldrin Jr. taken by fellow astronaut Neil Armstrong in the Figure. They were the first humans to walk on the moon. An astronaut weighs less on the moon than he would on Earth. This is because the moons gravity is weaker than Earths. The astronauts mass, on the other hand, did not change. He still contained the same amount of matter on the moon as he did on Earth. If the astronaut weighed 175 pounds on Earth, he would have weighed only 29 pounds on the moon. If his mass on Earth was 80 kg, what would his mass have been on the moon? [Figure 3] 

According to the above paragraph, the correct answer to the question "What's the difference between weight and mass?" is "Mass never changes"?

Om du har en massa på 50 kg på jorden, vad är din vikt i Newtons? Ett föremål med mer massa dras av gravitationen med större kraft. Massa och vikt är nära besläktade. Ett föremåls vikt kan dock förändras om tyngdkraften förändras. På jorden är gravitationens kraft densamma överallt. Så hur förändras gravitationens kraft? Det gör det inte om du stannar på jorden. Tänk om vi reser till en annan planet eller måne i vårt solsystem? Titta på fotot av astronauten Edwin E. Aldrin Jr. som togs av Neil Armstrong i figuren. De var de första människor som gick på månen. En astronaut väger mindre på månen än han skulle på jorden. Detta beror på att månarnas gravitation är svagare än jordens. Astronauternas massa förändrades däremot inte. Han innehöll fortfarande samma mängd materia på månen som han gjorde på jorden. Om astronauten vägde 175 pund på jorden skulle han bara ha vägt 29 pund på månen. Om hans massa på jorden var 80 kg, vad skulle hans massa ha varit på månen? [Figur 3] Enligt ovanstående stycke, det korrekta svaret på frågan "Vad är skillnaden mellan vikt och massa?" Är "Mass aldrig förändras"? ALTERNATIV: - nej - ja
