Car Lift/Initial Drop Retake: Proof of “Re-learning”
Please complete the following by filling in the data charts and answering the questions to
show a complete understanding of the concepts. Read directions carefully.
CAR LIFT - LENGTH VIRTUAL EXPERIMENT
Using the INCLINED PLANE simulation, choose two different lengths to represent a “short” and “long”
ramp or car lift. Choose DIFFERENT lengths than the original lengths of your ramps from lab. Assume
the height is 50 cm (0.5 meters), and the load is 5 Newtons. Test with ZERO FRICTION. Record the
measurements. If multiple numbers after the decimal, always record to ONE decimal place.
**Don’t forget to include UNITS after EACH number in your chart.
Distance object
moves

Applied Force
Work
PE
Short Ramp
Long Ramp
Analyzing your data:
Based on your data, what is the relationship between FORCE, DISTANCE, and WORK? What does it mean
to say “force/distance trade off?” Use data in your answer.

CAR LIFT - HEIGHT VIRTUAL EXPERIMENT
Using the INCLINED PLANE simulation, choose two different heights to represent a “short” and “tall”
height. Use one of your lengths from the above experiment, and continue to use 5 Newtons as your Load
and ZERO FRICTION. Record measurements. If there are multiple numbers after the decimal, always
record to ONE decimal place.
**Don’t forget to include UNITS after EACH number in your chart (if the number requires a unit!).
Height
Short Height
Tall Height
Applied Force
Work
PE
Analyzing your data:
1. Based on your data, what is the relationship between HEIGHT, APPLIED FORCE, and WORK?

____________________________________________________________________________________
____________________________________________________________________________________
2. Based on your data, what is the relationship between HEIGHT and POTENTIAL ENERGY? Use the
formula for PE to support your answer. How does this compare with what happened with PE in the
previous LENGTH simulation? Why?
____________________________________________________________________________________
____________________________________________________________________________________
____________________________________________________________________________________
3. NOW – look back at BOTH of the previous data tables for the length and height experiment. What do
you notice about the values for WORK and PE? Why was this happening, and what does this tell you
about the efficiency of the lift?

CAR LIFT - FRICTION VIRTUAL EXPERIMENT
Using the ROLLER COASTER SIMULATION, pick a number to represent a little amount and large
amount of friction. Pick a mass and height to control. Record the measurements. If multiple numbers
after the decimal, always record to ONE decimal place.
**Don’t forget to include UNITS after EACH number in your chart (if the number requires a unit!).
Friction
NO friction
Little Friction
Large Friction
Applied Force
Work
PE
Efficiency
Analyzing your data:
1. Based on your data, what is the relationship between the amount of FRICTION, APPLIED FORCE,
and WORK? (i.e. How do various amounts of friction affect force, and how does this affect work?)
Use the formula for work to support your answer.

3. How does adding friction affect efficiency? Look at the values for WORK and PE in this experiment
and use this data in your answer about efficiency.

INITIAL DROP EXPERIMENT
A new rollercoaster for Mt. Olympus theme park in Wisconsin Dells is being tested to determine
appropriate drop heights to ensure it is safe yet exciting for visitors. The release height is given to you.
Based on your knowledge of the relationship between release heights and speed, choose the correct speed
when you are given an option. Finally, use these numbers to calculate energies on the table below.
What is the formula for calculating PE? _____________________ Formula for KE? __________________
Mass of rollercoaster: 1,000 kg
Acceleration due to gravity: _____________(don’t forget a unit)
**Don’t forget to include UNITS after EACH number in your chart.
**Round to TWO decimal places.

HEIGHT and SPEED.

2. If Mt. Olympus decides to go with a heavier metal to build the rollercoaster carts, how will this affect
the speed at the bottom of the initial drop (ignoring effects of friction)? WHY DO YOU THINK THAT
IS?

3. Based on your data, what can you conclude about potential energy?
a. Where does the coaster have PE? Where is the PE zero?
______________________________________________________________________________
b. What factors determine how much PE the rollercoaster will have? Hint: look at formula!
______________________________________________________________________________
c. How will changing the height (and no other factors) affect PE? Why?
______________________________________________________________________________
______________________________________________________________________________
4. Based on your data, what can you conclude about kinetic energy?
a. Where does the coaster have KE? Where is the KE zero?
______________________________________________________________________________
b. What factors determine how much KE the rollercoaster will have? Hint: look at formula!
______________________________________________________________________________
5. Based on your data, what can you conclude about total energy?
a. Compare the total amount of energy at the top (initial) to the total amount of energy at the
bottom (final) using potential and kinetic values. What do you notice? Why is that happening?

b. In real life, would the values for initial potential energy and final kinetic energy be the same or
different? Why?
______________________________________________________________________________
______________________________________________________________________________
_____________________________________________________________________________
c. In real life, would the values for initial total energy and final total energy be the same or
different? Why? Hint: this question is DIFFERENT from part b. It is asking for the TOTAL
energy, including other forms such as heat energy. You should use the Law of Conservation of
Energy in your answer.
