Marble Tracks Potential Energy

Demo a marble run.

Marble tracks potential energy. When you release the marble gravity starts to pull it down the track. Potential energy is stored because of an object s elevation or height off the ground. The tracks stringless pendulums random answer devices an activation energy analogy an identical track race a high road low road track race and galileo s inertia track are homemade demonstration tools from his almost four decades of teaching. Kinetic energy is the energy of an object in motion.

When the coaster car starts going down the hill the potential energy is converted into kinetic energy or the. Lift marbles and boxes up. You can change how many are side by side and space them out to your liking. Quintanilla s students cooper olivia and hamza explore different kinds of energy and ways to track the movement of energy from one thing to another.

They work on straight and curved tracks. Potential energy is the energy that is stored in an object. This unit introduces potential energy and kinetic energy. Keeping track of energy.

An example of potential energy is a stretched out rubber band the farther you stretch it the more potential energy it has. Students will rapidly grasp that the marble gains speed as it falls from its release point and loses it again as it climbs back. Students consider the energy required when a ball rolls down a hill and strikes a. Download files and build them with your 3d printer laser cutter or cnc.

The total amount of energy in the system remains the same. Thingiverse is a universe of things. Science teacher bruce yeany uses this collection of physics marble tracks to introduce and reinforce his students ideas about perpetual and kinetic energy motion acceleration inertia and more. The marble also loses a small amount of energy due to friction or when it collides with the walls of the track.

Its potential energy is converted to kinetic energy the energy of motion. In this video i tried to explore or clarify several sugges. When the marble is placed at the top of the track it has potential or stored energy. Energy a roller coaster run initially without vertical loops is a good way to demonstrate the conversion between potential and kinetic energy.

If the marble has enough kinetic energy when it is launched off the end of the track it will successfully jump over the cars. In this science activity kids will use recycled cardboard tubes to create their own marble runs to explore potential and kinetic energy. Another example is a marble teetering at the top of a marble run. Updated video on the high road low road track race physics demonstration that i posted previously.

Motors are like the chains on the first big hill of a rollercoaster adding potential energy to your scene. This is called conservation of energy.
