  1. Roller Coaster Lab

  2. Objective:Compare & contrast the kinetic energy (KE) & potenetial energy (GPE)of a rollercoaster. !@#$%^%#$@%^&*(*&^$%@#@#%&^&**^%$#@##$%^^&&***&%$## Predict where the marble will have the greatest GPE & KE.

  3. Procedures a) Set up rollercoaster ramps & photogate timers. b) Measure height, mass, & velocity of the marble at 7 different positions. c) Record Data in Table. d) Graph data. e) Write a conclusion.

  4. DATA TABLE #1How do you calculate GPE? Measure: mass in Kg, Gravity (9.8 m/s2 & height in m. Don’t forget to convert grams to kilograms & cm to meters.

  5. Data Table #2 How do measure KE? Measure: mass in Kg, & velocity in m/s. Don’t forget to convert grams to kilograms & cm to meters. You also must ½ the mass & square the velocity

  6. Graph Position Vs KE & GPE Position is the ______________ variable; therefore goes on the _______ axis. Energy is the ______________ variable; therefore goes on the _______ axis. Draw a “ line of best fit” for both graphs use 1 sheet of graph paper.

  7. Title your graph.(also write your name on the paper) • Label the X &Y axis. • Scale the X & Y axis • Mark your data on the same graph • Draw a best fit line. • Color the lines KE in yellow & GPE in green • Write a conclusion. • Describe any sources of error.
