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]

Nine families displaced by a fire at Alamo Hills Apartments in March filed lawsuits Wednesday against the apartment complex. They allege that the complex could have done more to protect belongings they were forced to abandon in the aftermath of the blaze. Bernard Dempsey Jr., an attorney with Western Michigan Legal Services, the group that represents the tenants, said Alamo Hills gave the displaced families very limited opportunity to remove belongings. "They were given three days to get their stuff out, and if they couldn't get moved out in three days, their stuff was discarded," Dempsey said. "Alamo Hills just threw it out." Others, he said, lost possessions to looters after the March 23 blaze, which left 78 people temporarily homeless. According to the lawsuit, the tenants were prohibited from entering their apartments to retrieve possessions and were promised that the complex would provide security. A spokesperson for PM One, the company that manages Alamo Hills, could not be reached for comment. Nine separate suits were filed in 8th District Court, which handles civil claims of less than $25,000. "We're asking for the reimbursement of the value of their property and a small amount for stress -- $3,000 on top of their out-of-pocket expenses for their lost stuff," Dempsey said. "They're not looking to get rich off this. A lot of this is simply because they were treated so badly." Dempsey said most of the tenants who filed suits still live at the apartment complex, although many are trying to find homes elsewhere. "The new apartments (they were provided) were not in very good shape. That's actually one of the claims," he said.

What is evidence that the complex broke its promise to provide security?

It is almost summer time. Spring has been very long and very rainy. Winter was very warm and very long. In the winter the snows falls on the ground. It covers all the grass. It covers all the trees. It covers all the flowers. In the winter, the chipmunk goes to sleep. The chipmunk works all summer long to gather enough food for the winter. The chipmunk gathers berries. The chipmunk gathers pine cones. The chipmunk drops the pine cones off our roof and rolls them to her favorite hiding place. Boom! Boom! Boom! The pine cones sound so loud when they drop off the roof! The snow melts away in the spring. It is off the ground in our yard by the month of May. In June, there is still snow on the mountains. The snow on the mountains is still there until July. In May the grass starts to grow. In June, the flowers bloom again. In July, we go swimming in the lake. We get to play all summer. We do not have to go to school. We do not have to gather pine cones for food. We get to play outside and we get to have cook outs. We are not chipmunks. We are children. Our mom makes us lemonade in the summer time. Our mom takes us to the beach. Our mom lets us have a lot of campfires. Our mom mows the lawn. It is summer time and now we play for 90 days and the chipmunk works for 90 days. In the winter we work and go to school and the chipmunk gets to sleep. I am glad it is summer and I am glad that I am a human child and not a chipmunk. I am glad that we get to be awake through all the seasons. I like spring. I like fall. I like winter. My favorite time of all is, for sure, summer!
