Acceleration | Objective: To predict the time taken for a wheel to roll on its axle‚ down a slope using the energy method. Theory: Release Energy Method Ød or radius r After descent m kg I kg.m2 h v m/sec ØD or radius R Figure 1. Energy in a rolling wheel Referring to Figure 1 when the wheel is released from rest and subsequently rolls down the slope‚ it accelerates and hence gains energy. Now for a rolling wheel the kinetic energy has two components‚ translational due

Introduction Hama in Syria is famous for these water wheels‚ initially built by the Romans in what must be one of the most impressive engineering feats ever seen in a while. The current turns the wheels which contain small buckets which fill up with water and then spill out over to the aqueduct to its side... basically how to pump water from the river without using a pump. Apparently the wheels are all a-spin in the summer when there’s more water. History Norias were first developed in the Byzantine

MOTION: FERRIS WHEEL I. INTRODUCTION In this group project‚ we’ve decided to use a Ferris Wheel as an object to represent Uniform Circular Motion. A Ferris is a non-building structure consisting of a rotating upright wheel with passenger cars attached to the rim in such a way that as the wheel turns‚ the cars are kept upright‚ usually by gravity. Some of the largest and most modern Ferris wheels have cars mounted on the outside of the rim‚ and electric motors to
