=Terms to Know:=


 * Symbol = **Δ**
 * It means **change** (as in change of position).
 * The fourth letter in the Greek alphabet.
 * //Geography Connection//: a delta is also low, watery land formed at the mouth of a river. It is formed when the faster moving water carrying silt, sand, and small rocks that flows downstream in a river meets a bigger, slower moving body of water. (Think of going down a water slide and landing in a pool...there is a big __CHANGE__ of speed!) The sediments are often (but not always) deposited in the shape of a triangle.

**__Distance__**
Symbol = d

//x////f// //- x////i// //= d//

**__Position __**
//Definition//: An object's location at a given time. //__Example__//: If an object is at 100 meters for a starting point, 100 is it's position.

__**Equation **__ An //Equation// is a mathematical statement showing relationships between quantifiable variables. **__Final Position __** The position of an object at the end of a motion. 1234827968  **__Variables __**
 * Symbol: Xf 1234833160**

A factor or condition that can change and might affect the outcome of an experiment.

The act of changing position. **__Reference Point __** A specific location used to monitor change of position. Reference points can be on a moving object of in an object's environment. __**Initial Position**__
 * __Motion __**

The symbol is Xi.
Its definition is the position of an object at the start of a motion. Example: The starting poing is 50 its final positon is 150. So the initial position is 50.

__**Graph **__ A two coordinate system for displaying and analyzing an independent variable.

**__Independent and Dependent Variables __** Independent Variable- the variable that is changed on purpose by the experimenter in an expierement - goes on the x axis on a graph (horizontal)

Dependent Variable- the variable that is predicted or caused by the independent variable (the data) It is the variable that is obserbed and mesured in response to the independent variable. - goes on the y axis on a graph (vertical)

TIP- to determine which variable is the independent variable,ask yourself: "What do I know before the expiriment starts?"

Location and position mean the same thing.

Not on this test:
Speed (symbol:v) the distance traveled by an object in a unit of time. Speed is reported in standard units of distance per unit time, such as meters per second or kilometers per hour. 1234824555 1234828874
