HW: Science Fair project experiment
Date: 10/27 Goal: I can investigate the relationship between speed at the bottom of a pendulum and height of the period of its swing.
Bell Ringer: Name something you have seen in life that looks and acts like aPendulum ?
According to students’results, as the length (m) increases, What happens to the pendulum’s period (T)?
Based on the students’results,what would you predict the Period (T) to be if the length of the pendulum was (0.50)m?

2. What is the relationship between height and velocityIn table 2
Title: 10/7-8 Homework: In your notebook, write a summary of the relationship
between speed at the bottom of a ramp and both height and distance of the ramp.
Based on the results from your activity. Did the height or distance change have a greater effect on the speed at the bottom of the ramp? (5-10 sentences) This is on the weekly schedule on Mr. Stoll’s web
page
10/9 xXx Movie Calculation
Vin Deisel is trying to catch a jet boat to dismantle a bomb. He has to drive his GTO 50 miles to catch the
boat. The boat is traveling 10 miles up river at a velocity of 40 mile per hour.
1.How do you calculate the average velocity at which 50miles
10miles
the GTO must travel?40mi./h
2. Is this possible in real life? Why or Why not?
