What is Mechanical Energy?
  • Mechanical energy is the energy that an object possesses due to its motion or position.
    Example:
    • A moving bicycle has mechanical energy — due to its motion.
    • A flowerpot kept at a height has mechanical energy — due to its position.
    • GIF Watch: what is Mechanical Energy Animation for "What is Mechanical Energy". A short looping GIF, three or four beats, drawn in the flat classroom style of the chapter. Beat 1 — Mechanical energy is the energy that an object possesses due to its motion or position. Beat 2 — We will quantify mechanical energy by using the concept of work. Label every arrow and quantity, name the direction each force or motion acts in, and hold the last frame for a moment before the loop starts again.
  • We will quantify mechanical energy by using the concept of work.
What are the 2 types of Mechanical Energy?
Type Energy due to Example
Kinetic energy Motion of the object A moving bicycle, a rolling ball
Potential energy Position (or shape) of the object A flowerpot at a height, a stretched rubber band
  • Lets study Kinetic Energy first.
