Marble Roller Coaster Potential Energy

Build your own marble roller coaster in this project and find out.

Marble roller coaster potential energy.

Marbles have a limited amount of energy so encourage the students to plan their roller coaster according to how much energy the marble has. Energy systems are explained using focus words including momentum velocity acceleration inertia friction and gravity. Demo a marble run. When the marble is released its potential energy transforms into the energy of motion or mechanical kinetic energy.

Abstract if you d like to investigate the physics of amusement park rides then this project is for you. The marble rolls because it has gravitational potential energy. At the end of the roller coaster unit students should be able to describe what causes variations in the amount of potential energy an object has. Marble roller coasters are science based interactive toys that work on the principles of physics particularly changing potential energy into kinetic energy.

This kinetic energy will never be greater than the marble s original amount of potential energy. You ll build a roller coaster track for marbles using foam pipe insulation and masking tape and see how much the marble s potential energy at the beginning of the track is converted to kinetic energy at various points along the track. Converting potential energy to kinetic energy have multiple groups work together to build a single larger roller coaster. Students explore our obsession with roller coasters since their introduction in the 17th century.

As it moves higher it has more potential to fall to earth increasing its kinetic. As it rolls over the hills and through the loops of the roller coaster it experiences a continual interchange of potential and. This unit introduces potential energy and kinetic energy. Start the coaster high and test regularly.

Given students the potential and kinetic videos clips at the end of the roller coaster unit students should be able to explain the difference between potential and kinetic energy. They re miniature versions of the types of roller coasters you d find at amusement parks and they include twists turns and loops. For example a coaster could go between three levels a desk a chair and the floor. The same principles apply to a real roller coaster.

Before a roller coaster is launched it is slowly pulled up to the highest part of the track by a motor driven chain. Since potential energy is only dependant on a change in height changing the run should have little to no effect on how far the marble travels. Background roller coasters rely on two types of energy to operate. Potential energy is gathered by an object as it moves upwards or away from the earth.

Gravitational potential energy and kinetic energy. Why we love roller coasters.
