What are the forces on the marble.

A marble rolls around the inside of a semicircular track.

Pool noodle marble run via homespun threads an easy and inexpensive way to make a long track marble run using noodle. As the marble leaves the track at point 0 does it follow path a path b or path c. If a marble rolls along the inside of a semicircular track how does it leave the track. A marble rolls along the inside of a semicircular track made of copper tubing that is lying on a level table that is parallel to the floor.

Marble rolls pretty far but if i set the end of the tube up on 3. Your expression for the velocity looks right. On the other hand you need to take account of the energy of the sphere rolling which is stated explicitly. Assuming a frictionless surface and a marble being rolled on a flat surface around a semicircular track think half of an o how does the marble leave the track once it reaches the end.

Any slower and gravity will pull the marble in a tighter arc than the track ie it will fall off. 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. After you introduce longer cardboard tubes the second day you ll probably.

A marble rolls along the inside of a semicircular track made of copper tubing that is lying on a level table that is parallel to the floor.

The minimum force on the marble is mg normal force 0 so the minimum speed is when. Session there may be reports of getting the marbles to roll all the way across the floor around corners and even up and down like roller coaster cars. But we have to get a few other things taken care of. As the marble leaves the track at point 0 does it follow path a path b or path c.

The marble leaves the semicircular track and follows path b. Gravity and possibly a normal force. Kinetic marble track around the top of a room. Does it leave straight curve outwards away from the track or curve.
