Physics: 6: 5-7 Conservative and non-Conservative Forces


Reading Preparation

Text Reading: Giancoli, Physics - Principles with Applications, Chapter 6: Sections 5-7

Study Points

Key Equations

  • Non Conservative Forces W net   = W C   +   W NC    =   Δ KE W C   =   Δ PE W NC    =   Δ KE   + Δ PE  
  • Conservative Forces W NC    =   0 E   =   Δ KE   + Δ PE  

    KE   =   1 2 m v 2 PE   =   mgh

Study Activity

If we drop a ball and it bounces, each succeeding bounce is a bit lower. This guided exercise walks you through the "observation" of a bouncing ball. Using the pictures of the starting height and the bounce height, we can calibrate the ball's energy loss over time.

Click HERE to begin investigating how a ball loses energy as it bounces. There are five trials. You will need a paper and pen or a notepad program to capture your "observations" and a calculator to calculate the energys involved. Once you have your data, you will be able to use the graphing tool incuded in the exercise to graph your data.

Lab Work

If you want lab credit for this course, you must complete at least 12 labs (honors course) or 18 labs (AP students). One or more lab exercises are posted for each chapter as part of the homework assignment. We will be reviewing lab work at regular intervals, so do not get behind!
