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]

Question: "When does the force of gravity change"

Answer: "When the weight changes"

Response: no

In Colombia, the drug-financed guerrillas trying to seize the country and destroy democracy include M-19, which Castro has clearly backed. Robert Merkel, a former U.S. attorney handling drug indictments in Florida, doesn't think for a minute that Castro's much publicized trials of high officials engaged in the drug trade mean he has broken off with the Medellin drug cartel. "If the cartel succeeds in blackmailing the Colombian authorities into negotiations, the cartel will be in control and Fidel can exploit his past relationships with them," he told the Journal's David Asman recently. The struggle against the drug lords in Colombia will be a near thing. This week, the government arrested Jose Abello Silva, said to be the fourth-ranking cartel leader. He will probably be extradited to the U.S. for trial under an extradition treaty President Virgilia Barco has revived. Later, another high-ranking trafficker, Leonidas Vargas, was arrested and 1,000 pounds of dynamite seized. Mr. Barco has refused U.S. troops or advisers but has accepted U.S. military aid. President Bush has agreed to meet within 90 days with Mr. Barco, President Alan Garcia of Peru and President Jaime Paz Zamora of Bolivia to discuss the drug problem. It might not be a bad idea to do that sooner, rather than later. After the Panama fiasco, they will need some reassurance. Certainly, the Colombian press is much in need of that.

Question: "What country revived extradition treaty with the United States?"

Answer: "Virgilia Barco"

Response: no

Magnets are able to place a force on certain materials. This force is called a magnetic force. The force a magnet exerts is a little different from the forces you may normally think about. You exert a force on a book when you lift it. You also exert a force on the pedals of your bicycle. In both those cases, those forces cause a change. The change you see in both these cases is called motion. Magnets, too, can produce change. They can produce motion just like you do. Unlike you, magnets do not have to touch something to exert a force. A magnetic force is exerted over a distance. Thats right, a magnet can push or pull certain items without ever touching them. Thats how the maglev train works. Do you know another type of force that does not require objects to touch? These forces are known as non-contact forces. Another type of non-contact force you may be familiar with is gravity. Gravity too can cause changes in motion. Gravity holds our moon in orbit without touching it.

Question: "What is another type of force that does not require objects to touch?"

Answer: "Magnetic force"

Response: no

The film is set in Igloolik in the Eastern Arctic wilderness at the dawn of the first millennium . http://atanarjuat.com/legend/legend_film.php The wind is blowing over a bleak snowy landscape while a man tries to herd away some marauding dogs .

Inside a stone house a strange shaman by the name of Tungajuaq , who comes from up north , is singing playfully to the gathered community and camp leader Kumaglak . But among the spectators there are some mistrustful faces . Flash forward to another day . Qulitalik is bidding goodbye to his sister Panikpak , wife of Kumaglak , promising to come if she calls for help in her heart . She gives him her husband's rabbit's foot for spiritual power . Qulitalik tells his sister , '' Tulimaq is the one they 'll go after now . '' It seems that Qulitalik is leaving to escape a threat , and the hope is that one day he will return to help . As Panikpak watches him leave , we hear a voice-over from a woman : '' We never knew what he was or why it happened . Evil came to us like Death . It just happened and we had to live with it . '' Flash back to the original scene in the stone house . The visitor and the camp leader Kumaglak are in a '' friendly '' spiritual duel involving binding in leather thongs . But Panikpak is startled when the stone lamp in front of her breaks in half , and , to the horror of those present , Kumaglak falls over dead .
