Problem Set C

Overview:

Problem Set C targets your ability to analyze and interpret velocity-time plots of an object's motion. There are at least two skills needed to be successful in Problem Set B:

1. Velocity-time plots represent variations in an object's velocity over the course of time. As such, the slope of such graphs provides a velocity change-to-time ratio; this ratio represents the acceleration of the object. The first required skill involves the ability to determine the slope of the line at any location along the graph. The task of determining the slope of a line can be reviewed at The Physics Classroom.
2. The line on a velocity-time plot, the actual time axis and two imaginary vertical lines drawn at two specified points in time can represent a rectangular, triangular or complex area. A determination of this area yields information about the displacement of an object during the specified time interval. The task of determining the area between the line and the time axis can be reviewed at The Physics Classroom.
