Vocabulary 5th Diego
| Term | Definition |
|---|---|
| Acceleration | Acceleration is the act of increasing speed. When you buy a sports car, you want one that has great acceleration, so it can go from zero to 60 miles an hour in no time. |
| Displacement | Displacement occurs when one party unfairly or inappropriately replaces another. If you arrive at work to find someone else sitting at your desk, you might want to complain to your boss about your recent displacement. |
| Speed | Speed most often describes acceleration or a high rate of motion. When something picks up too much speed, it can run off course, like a kid on a bike zooming uncontrollably down a steep hill. |
| Mass | Anything that has weight and shape has mass. In fact, mass is the quality that gives things weight anywhere there's gravity. |
| Inertia | Inertia is resistance to change. You hate looking at people's feet and yet you stay in your job as a shoe salesman year after year. |
| Average | If something is average, it's ordinary and not very special. You might say a movie was average if you thought it was just okay. |
| Momentum | Momentum is generally used to mean increasing forward motion. A boulder rolling down a hill gains momentum. So does a great idea, a team on a winning streak, or the economy. |
| Velocity | If your rocket is traveling at maximum velocity, it means it can't go any faster. Velocity is quickness of motion or action. |
| Newton's 3 laws | Newton's laws of motion are three physical laws that, together, laid the foundation for classical mechanics. They describe the relationship between a body and the forces acting upon it, and its motion in response to those forces. |
| Biosphere | A biosphere is a place where organisms live. You wouldn't want to travel beyond the earth's biosphere, unless of course you are an astronaut. |
| Habitat | Your habitat is the environment you are accustomed to living in. Zoos usually try to mimic the habitats of the animals they keep, housing bats in a nocturnal house and monkeys in a cage with trees to climb and swing from. |
| Carry Capacity | the number or quantity of people or things that can be conveyed or held by a vehicle or container. |
| Immigration | Immigration is the process of moving to a new country to stay. New York's Ellis Island was considered a gateway for European immigration to the United States during the early 1900's. Nowadays, people immigrate through airports instead of islands. |
| Emigration | Emigration is when a person leaves his or her home country to live in another country indefinitely. |
| Symbiosis | Symbiosis, a noun, tells about the relationship between living things that helps all of them stay alive, like the symbiosis between bees that eat nectar from flowers that get cross-pollinated when the bees move from one to the next. |
| Demographic | Advertising agencies like to schedule their commercials in television shows that appeal to the 18-49 demographic, because this segment of the population has a lot of spending power. |
| Limiting Factors | A limiting factor is a variable of a system that, if subject to a small change, causes a noticeable change in an output or other measure of a type of system. |
| Extinction | Extinction is when all members of a particular group die. Most often, we use it to discuss animal species. Many fear that the tiger is headed for extinction because of development and hunting. |
| Density | Density describes how compact or concentrated something is. For example, suppose you have two boxes, one large and one small. However, they both weigh the same. That means the small box has a higher density than the large box. |
