9/11 Newton's Cradle Analysis

Your Newton's Cradle should be built. Determine experimentally the period of one swing of one ball on your Newton's cradle. Use this, and the formula for a pendulum, to calculate the expected length of the pendulum. Compare this to the measured length of the string and the ball. Determine the change in x the far ball goes through if it is hit with a single ball. Do this for a ball that is lifted to h1 and h2. Use Es= 1/2k(change in x)2 to calculate the k of the ball, which is acting as a spring. Remember, in theory, Es should be equal to PE of the ball (m(ball)*accel(g)*height(above ground). Write up the results, and take a picture of your Newton's cradle. Submit both to me via email.

Skim through Lesson 1    Most of this will be review, so move quickly, starting here


Pay careful attention to the animations.

Answer the questions in your notes.

Let me know when you get to the earthquake simulation.
