On an actual roller coaster, there are many ups and downs, and each of these is accompanied by transitions between kinetic and potential energy. Assume that no energy is lost to friction. At any point in the ride, the total mechanical energy is the same, and it is equal to the energy the car had at the top of the first rise.

To build a support strut: Cut a 6.25 cm (2.5 inch) wide strip of paper. Draw four parallel lines that divide it into five 1.25 cm (0.5 inch) wide strips. Cut inward 2.5 cm along these lines from one edge. Fold along the lines to form a square shape (so two of the segments overlap), and use tape to hold in place.

roller coaster variables. A ball moves along a curved track. We assume that the ball cannot leave the track, but is free to move along its length. We have two variables. p = position on the track (measured by path length along the track) v = velocity. We pick some point on the track to be position p = 0 and pick a direction along the track to ...

Conclusion: In this lab we measured the acceleration of a rolling ball down a ramp at a specific height. Our variables in which we used to determine speed was a little metal ball, and a metal black ramp we placed the ball on to measure its speed. We marked this ramp at each distance in which we were starting the ball from.

Omtec PBT Ball Transfers retract below the conveyor ball rollers allowing items not transferring to move on the rollers unaffected by the ball transfer strips. Omtec standard is to place the first and last pop up ball transfer 1.25 inches (31.75MM) C/L from each end of the main body (between frame dimension). The other pop ups are evenly spaced.

rolling elements, they are classified into ball bearings or roller bearings, and they are further segregated by differences in their design or specific purpose. The most common bearing types and nomenclature of bearing parts are shown in Fig.1.1, and a general

In this hands-on activity—rolling a ball down an incline and having it collide into a cup—the concepts of mechanical energy, work and power, momentum, and friction are all demonstrated. During the activity, students take measurements and use equations that describe these energy of motion concepts to calculate unknown variables and review the relationships …

Rolling bearings include: ball bearings, roller bearings (tapered roller bearings, spherical roller bearings, cylindrical roller bearings and needle roller bearings) and combination ball/roller bearings. In addition to reducing friction, bearings support loads. A load is defined as a force applied to a bearing.
