Marble Roller Coaster Background Research

It must have at least 2 hills including the starting point one loop cannot have a top and must be free standing.

Marble roller coaster background research.

They re miniature versions of the types of roller coasters you d find at amusement parks and they include twists turns and loops. Get hands on exploring what kinds of loops are possible how energy changes during a ride and how the laws of motion come into play. Gravitational potential energy is the energy an object has stored because of. In this lesson students will prepare to construct a marble roller coaster by completing background research on roller coasters.

If you followed the guidelines discussed in the background section you should have been able to design a working roller coaster. This is a good opportunity to explain the negative effects of momentum. Gravitational potential energy and kinetic energy. Roller coasters and marble runs offer an engaging platform for invention engineering and physics based investigation.

Background roller coasters rely on two types of energy to operate. Your roller coaster cannot be prefabricated or from a kit. You ll build a roller coaster track for marbles using foam pipe insulation and masking tape and see how much of an initial drop is required to get the marble to loop the loop it s a great way to learn about how stored energy potential energy is converted into the energy of motion kinetic energy. If it s too flexible then it s hard for the loop to keep its shape.

The foam pipe insulation needs to be the stiff kind. Potential energy is gathered by an object as it moves upwards or away from the earth. If a curved track is not banked the marble may fly off of the edge of the track. With a roller coaster this is acheived by pulling the train up a lift hill to the coaster s highest point.

Research design and build a roller coaster. Marble roller coasters are science based interactive toys that work on the principles of physics particularly changing potential energy into kinetic energy. In roller coaster construction this is called track banking. Plan your 60 minute lesson in science with helpful tips from kara nelson.

Building a simple marble run or tube based coaster is only the beginning. A marble travelling forward will continue moving in that direction because of it s momentum. Because some energy is always lost to friction your initial hill.
