Design Challenge:
Can you construct a rollercoaster that
will carry a marble from the top to the bottom using gravity and forces?
Questions:
How is your design similar and different
from a real rollercoaster?
What features in your design were
necessary for the marble to roll all the way to the end?
What problems did you face in your design
process?
How did you improve your design?
How does friction affect your marble?
How are potential and kinetic energy used in a rollercoaster?
Vocabulary
Gravity: Force of attraction of objects to the centre of the earth
Potential energy: Stored energy that an object or substance has because of it’s position or condition. For example, rollercoaster at the top of the track. Potential energy can change (transform) into kinetic energy
Kinetic energy: Working energy that an object or substance has because of its’ motion. Examples, rollercoaster going down a hill, waterfall
Friction: Surface resistance to motion
