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 did Edwin E. Aldrin Jr. and Neil Armstrong weigh less on the moon?

The violent arena of domestic abuse litigation has grown a bit more volatile here, now that a judge has decided to hold two women in contempt of court for returning to men who had been ordered to stay away from them. "You can't have it both ways," said Judge Megan Lake Thornton of Fayette County District Court in recently fining two women $100 and $200 respectively for obtaining protective orders forbidding their partners from contacting them, then relenting and contacting the men. Ruling that the order was mutually binding, Judge Thornton also cited the men for contempt. "It drives me nuts when people just decide to do whatever they want," said Judge Thornton, who is experienced in the state's thick domestic abuse docket, which produces close to 30,000 emergency protective orders a year. Kentucky officials say there is a virtual epidemic of abusive relationships in the state. Judge Thornton's ruling has alarmed advocates for battered women, who plan to appeal it. The advocates say the finding goes beyond existing law and is unrealistic because some renewed contacts often prove unavoidable in domestic abuse cases, which involve economic and family dependency and other complications of daily living. The state office on domestic violence has pointedly agreed, warning that the ruling could cause abused women to hesitate in bringing their plight before the courts for fear of being chastised for their trouble. "The reality is it's easy to say they should never have contact," said Sherry Currens, executive director of the Kentucky Domestic Violence Association, an advocacy and legal protection group. "But we're talking about people in long-term relationships. They may have children in common. It's pretty hard to say, 'Never speak again.' People have financial difficulties. They may love the partner. It's not an easy thing." But Judge Thornton declared in court, "When these orders are entered, you don't just do whatever you damn well please and ignore them." The ruling stunned Cindra Walker, the lawyer for the two women, who is with Central Kentucky Legal Services, which represents many of the thousands of indigent women caught in abusive relationships. "For over five years, I've been in court practically every day on these abuse cases," Ms. Walker said, "and I've never before had a victim threatened with contempt."

What prompted Judge Megan Lake Thornton to make the statement: "You can't have it both ways."

The world can be divided into three climate zones. The first climate zone is the polar zone. As it sounds, the polar zone is near earths poles. The polar zone has very long and cold winters. Brrr!!!! Near the equator is the tropical zone. The tropical zone is known for being hot and wet. Between these two zones is the temperate zone. Temperatures there tend to be mild. Its not too hot and not too cold. You might expect places near the equator to be hot and wet. Thats not always the case. Sometimes there are other factors at work. These factors can affect the local climate type or a region. Oceans and mountain ranges can have a major impact. They can greatly influence the climate of an area. Many factors influence an areas climate.
What can influence the climate of the area?
