*8th Grade State Science Standard for Motion

1. The velocity of an object is the rate of change of its position.

As a basis for understanding this concept, students know:

a. position is defined relative to some choice of standard reference point and a set of reference directions.

b. average speed is the total distance traveled divided by the total time elapsed. The speed of an object along the path traveled can vary.

c. how to solve problems involving distance, time, and average speed.

d. to describe the velocity of an object one must specify both direction and speed.

e. changes in velocity can be changes in speed, direction, or both.

f. how to interpret graphs of position versus time and speed versus time for motion in a single direction.

9. Scientific progress is made by asking meaningful questions and conducting careful investigations.

As a basis for understanding this concept, and to address the content the other three strands, students should develop their own questions and perform investigations. Students will:

d. recognize the slope of the linear graph as the constant in the relationship y=kx and apply this to interpret graphs constructed from data.

f. apply simple mathematical relationships to determine one quantity given the other two (including speed = distance/time, density = mass/volume, force = pressure x area, volume=area x height).

g. distinguish between linear and non-linear relationships on a graph of data.
