Kinematics Investigation

Activity Overview

In this activity, students solve trigonometric equations and investigate kinematics. They calculate and graph the displacement, velocity, and acceleration of trigonometric functions.

Before the Activity

  • Download TI Connect™ using the TI Connectivity Cable
  • See the attached PDF file for detailed instructions for this activity
  • Print pages 1 - 4 from the attached PDF file for your class
  • During the Activity

    Distribute the pages to the class.

    Follow the Activity procedures:

  • Enter equations of trigonometric functions and graph a plot
  • Solve the equations over a given domain
  • Find the point(s) of intersection of the graphs
  • Calculate the period, amplitude, and the vertical shift of the graphs
  • Sketch graphs for one period and label the intercepts and turning points
  • Determine the maximum and minimum points
  • Find the equation of the tangent to a curve at a given point
  • Study the Simple Harmonic Motion

  • Find the displacement, velocity, and acceleration of a particle traveling in a straight line
  • Interpret the graphs of displacement time, velocity time, and acceleration time
  • After the Activity

    Students answer the questions on the activity sheet.

    Review student results:

  • As a class, discuss questions that appeared to be more challenging
  • Re-teach concepts as necessary
