Marble Loop The Loop Physics

When you let go of the marble its potential energy is converted into kinetic energy the energy of motion.

Marble loop the loop physics.

Build a miniature roller coaster and see if you can get marbles to go the distance and upside down. When the marble finally gets to the floor it has all kinetic energy and no potential energy. I solve the loop the loop first year undergraduate and ap physics problems. On the other hand you need to take account of the energy of the sphere rolling which is stated explicitly.

Loop the loop with a little physics. Chris got asked how fast you would need to be going to complete a loop the loop this is what we got. It takes extra energy for the marble to stay on the track so it has to slow down when it goes through the loop. 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.

The loop is tricky. But we have to get a few other things taken care of. Abstract this is a really fun project even if you don t like going on roller coasters yourself. First we need to find the minimum speed required at the top of the loop.

Your expression for the velocity looks right. A loop the loop track consists of an incline that leads into a circular loop of radius r. First the center of the marble doesn t move from 0 to 2r it moves from r to 2r r so the potential energy due to this is smaller than mg 2r which is what you had in your expression. We are going to find the minimum speed you require to complete the loop we ll do this via an energy argument.
