Main Kinematics & Dynamics Understanding Motion Unit I:Kinematics & Dynamics

Understanding Motion

Learning Objectives:

  1. Define the following terms: uniform motion, non-uniform motion, stroboscope.
  2. State and explain whether an object is in motion with reference to another object.
  3. Understand that motion is measured over a time interval.
  4. Recognize that periodic motion can be used to measure time.
  5. Compare uniform and non-uniform motion.

Key Concepts:

  • Physics is a systematic, organized, and logical science. It is necessary to have a structured approach when solving any type of problem in science.
  • Motion is relative to the position of the observer. Different observers may perceive the motion of an object in entirely different ways.
  • An object is in motion if its position changes with respect to an observer.
  • Motion is measured over a time interval such as s, min, h.
  • An object that undergoes periodic motion (pendulum, recording timer, stroboscope) can be used to measure time and may be calibrated against a standard measurement of time.
  • Motion can be either uniform or non-uniform.
