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: "On another planet or moon in the solar system"

Response: yes

Earthquakes seemed to outline a special feature of earth's crust. Earthquakes let scientists know where the crust was moving. This led to the discovery that the Earths crust was broken up into regions, or plates. Earthquakes happen most often along these plate boundaries. This was evidence that continents can move. The movements of the plates are called plate tectonics. The Earths crust is divided into plates. There are about a dozen large plates and several small ones. Each plate is named for the continent or ocean basin it contains. Scientists know he plates are in motion. They now know the direction and speed of this motion . Plates dont move very fast. They move only a few centimeters a year. This is about the same rate fingernails grow. So you might wonder, what could cause this motion? What supplies the energy to cause this change?

Question: "How many plates is the earth's crust divided into?"

Answer: "More than 10 large ones"

Response: yes

(CNN) -- Women seeking an abortion in Texas will have to view a picture of the embryo or fetus and hear a description of its development before having the procedure, under a law that takes effect September 1. The bill stirred some controversy in Texas, but it easily passed through the state House and Senate, both of which are controlled by Republicans. It was signed into law Thursday by Republican Gov. Rick Perry. The law says that at least 24 hours before an abortion is performed, women must undergo a sonogram, a procedure that uses ultrasound to create an image. The doctor, then, is required to give, "in a manner understandable to a layperson, a verbal explanation of the results of the sonogram images, including a medical description of the dimensions of the embryo or fetus, the presence of cardiac activity, and the presence of external members and internal organs," the law states. There are some exceptions, including pregnancies that resulted from sexual assault, incest or other violations of law. Women seeking abortions also are exempt if the fetus has been found to have an irreversible medical condition that will cause a disability. "Governor Perry was pleased to sign this important legislation, which bolsters our efforts to protect life by ensuring Texans are fully informed when considering such an important decision," said his deputy press secretary, Lucy Nashed. Critics say the new law is unnecessary. "What no one is focusing on is that this is a mandate to humiliate women who want an abortion," said Yvonne Gutierrez, vice president for public affairs at the Planned Parenthood Trust of South Texas. Texas already requires a 24-hour consent period, and the new law will simply add emotional and financial costs to those seeking abortions, she said.
