• Watch the roller coaster from: http://www.funderstanding.com/coaster

• Answer the following questions:1. Why didn’t the roller coaster make it all the

way through at first?2. What could you change to make it work?

(include all possibilities).

Roller Coasters

Challenge: design and create a roller coaster that lets the marble travel all the way through.

Requirements:Marble must land in the cup at the end of the roller coasterHave at least 1 hill and 1 loopInclude a diagram with PE and KE labeled Record the length of the roller coaster, time it takes for the marble

to go through it, mass of the marble, and height of the first hillCalculate speed of the marble, and potential energy using

formulas.Conduct 5 trialsAnswer the conclusion questionsCreate a poster showing your design and how you have applied

your understanding of potential and kinetic energy

Roller Coaster Physics

phet.colorado.edu/en/simulation/energy-skte-park

• What forces are acting on the roller coaster that might affect its speed?

Friction

Gravity

- due to surfaces touching- the frictional force on the roller coaster is between the track and the marble.- Air resistance may also be included here

- due to the pull of gravity to the center of the Earth.- the gravitational force pulls the marble down

This arrow represents friction. It is pushing against the movement of the roller coaster.

This arrow represents gravity. It is pushing down on the roller coaster.

Be prepared to draw arrows representing friction and gravity on your roller coaster poster

Forces on a Roller Coaster

Use a bar graph to represent potential energy (PE) and kinetic energy (KE) at different places on the roller coaster.

A

B

C

D

At point A, a bar graph for PE and KE would look like this:

What would a bar graph look like for points B, C and D?

Be prepared to label important areas for PE and KE on your roller coaster poster.
