Problem Set B

 

Overview:

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

  1. Position-time graphs represents variations in an object's position over time. Thus, an inspection of the values being plotted along the vertical axis allows one to determine position values and changes in position. These axis values are related to the distance and displacement for an object's motion. The distinction between distance and displacement can be reviewed at The Physics Classroom.
  2. Slopes of such graphs yield a ratio of the position change to time for any specified interval of time. As such, the slopes are equivalent to the velocity of an object. Velocity (slopes in this case) is a vector quantity that has a direction associated with it. Mathematically, the velocity direction is represented by a positive or a negative value. Upward-sloping lines are associated with positive velocities and downward-sloping lines are associated with negative velocities. The task of determining the slope of a line can be reviewed at The Physics Classroom.
