 * Note:** Physics Olympics will be April 7th @ Solanco High School at 4 pm. Any student interested in doing this please see Mr. Manning.

Review of Lab Homework Review Page 2 Again Centripetal Force and Acceleration Notes
 * Todays Agenda:**

Question 1: Can be straightened out because it is a quadratic relationship. Velocity must be squared to straighten out the graph. F~v^2 Question 2: This is also a quadratic relationship and can also be straightened out. Velocity must be squared to straighten the graph. Radius is proportional to the velocity squared. Question 3: This is not a quadratic relationship because the graph curves down. This is called an inverse graph. The equation for an inverse is y=1/x. Below is a graph of the inverse relationship:
 * Centripetal Forces Lab Review:**

Question 4: Force is proportional to mass. Same radius at same speed, but one had a lighter mass.

Equation we can make from this information: Centripetal Force Fc = m(v^2)/r

After Reviewing the lab, Mr. Manning gave the class some time to discuss page 8 in groups, before submitting it.


 * Homework:** None
