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]

Why does an astronaut weigh less on the moon than on earth

Assisting Zionist causes Einstein was a figurehead leader in helping establish the Hebrew University of Jerusalem, which opened in 1925, and was among its first Board of Governors. Earlier, in 1921, he was asked by the biochemist and president of the World Zionist Organization, Chaim Weizmann, to help raise funds for the planned university. He also submitted various suggestions as to its initial programs. Among those, he advised first creating an Institute of Agriculture in order to settle the undeveloped land. That should be followed, he suggested, by a Chemical Institute and an Institute of Microbiology, to fight the various ongoing epidemics such as malaria, which he called an "evil" that was undermining a third of the country's development. Establishing an Oriental Studies Institute, to include language courses given in both Hebrew and Arabic, for scientific exploration of the country and its historical monuments, was also important. Chaim Weizmann later became Israel's first president. Upon his death while in office in November 1952 and at the urging of Ezriel Carlebach, Prime Minister David Ben-Gurion offered Einstein the position of President of Israel, a mostly ceremonial post. The offer was presented by Israel's ambassador in Washington, Abba Eban, who explained that the offer "embodies the deepest respect which the Jewish people can repose in any of its sons". Einstein declined, and wrote in his response that he was "deeply moved", and "at once saddened and ashamed" that he could not accept it.

(CNN) -- We'll let you finish, but The Muppets have the best Instagram account of all time. The feed was launched just over a month ago as part of a promotional push for their upcoming movie, "Muppets Most Wanted." But in between quippy posters and ads for the film, which is a sequel to 2011's blockbuster "The Muppets" with Jason Segel, there are ingenious "selfies" from the Muppets crew. In fact, the first post was a coy snapshot from Kermit, Miss Piggy and Gonzo, with a filter in full effect: And the selfies grew more adorable -- and more hilarious -- from there: We now have evidence of the time Animal burst in on Beaker in the bathroom. And we know what Gonzo does after a hard day of stunts. "Gonzo treated himself to a massage today to try to work out all of his stuntman kinks. Even weirdos need pampering. #bougielife #yolo," reads the caption to this pic: The Muppets' curmudgeonly yet lovable critics, Statler and Waldorf, are still trying to get the hang of taking the perfect selfie -- "This is the fanciest calculator we've ever seen!" they were heard saying when the photo was taken -- while Rowlf is clearly a selfie king. From the Swedish Chef to Miss Piggy's evil alter ego, everyone has gotten in on the first-person photo sessions. The only people noticeably missing from the account are the Muppets' human co-stars in "Muppets Most Wanted," like Tina Fey, Ty Burrell and Ricky Gervais. As with the first "Muppets" film, which also starred Amy Adams, Chris Cooper and Rashida Jones, the "Muppets" sequel has plenty of human star power. In addition to Fey and Gervais, "Muppets Most Wanted" also has appearances from Tom Hiddleston, Salma Hayek, Stanley Tucci and Lady Gaga.
