Vectors and Vector addition
In this lab we will investigate vectors using a force board. The force board is
marked in degrees from 0o to 360o. Let the 180 0 line represent the x axis
and the 90 270 line represent the y axis. You must be familiar wit

Investigating Distance and Speed; Displacement and Velocity
Introduction:
This investigation is designed to help you learn about distance and speed,
and distinguish it from displacement and velocity.
Distance is the length of the path traveled by an
