Learning Target: An object in motion changes position.
Learning Target: An object in motion changes position.
Draw a picture below to represent the motion described in the scenarios below.
- An ant crawls across the top of your shoe, from left to right
- A hiker walks from the beginning to the end of a hiking path
How can we describe where the ant and the hiker will end up?
The position of a place or an object is the location of that place or object. Often you describe where something is by comparing its position with where you currently are. You might say that a classmate is sitting 5 feet away from you, or post office is two blocks south of your house. Each time you identify the position of an object, you are comparing the location of the object with the location of another object.
How do we get from the north parking lot to the Dark Voyage ride?
How do we get from the Adventure River to the Bermuda Triangle?

Describing a Position
A location to which you compare other locations is called a reference point. You can also describe a position using a method that is similar to graphing. The latitude and longitude system describes position using degrees.
Longitude describes how many degrees east or west a location is from the prime meridian
Latitude describes how many degrees north or south a location is form the equator.

Motion is a change in position.
Describe the long jumpers motion using the terms horizontal and vertical.
Motion is the change of position over time. As she jumps both her horizontal and vertical positions change. If you missed watching her jump, you would still know that motion occurred because of the distance between her starting and ending positions.
Describing Motion
How would you describe the motion shown in the images above?
A change in an object's position tells you that motion took place, but it does not tell you how quickly the object changed position. The speed of a moving object is a measure of how quickly or slowly the object changes position
What is relative motion? Describe it in words and draw a picture of it.
