    the first hill at the beginning of the ride‚ but after that the coaster must complete the ride on its own. You aren’t being propelled around the track by a motor or pulled by a hitch. The conversion of potential energy to kinetic energy is what drives the roller coaster‚ and all of the kinetic energy you need for the ride is present once the coaster descends the first hill.. Once you’re underway‚ different types of wheels help keep the ride smooth. Running wheels guide the coaster on the track

    described and analyzed as an object which gravity is the only force acting on it as it undergoes independent vertical and horizontal motions. 11. How does a trebuchet store energy and transfer it to the projectile? It stores energy to launch a projectile by converting potential gravitational energy into useable kinetic gravitational energy. This is transferred through gravity pulling down a counter weight attached to one end of a lever which then raises the other end‚ launching the projectile from a sling

    disk of radius R = 0.25 m has a string wrapped around it‚ and a m = 3 kg weight is hanging on the string. The system of the weight and disk is released from rest. a) When the 3 kg weight is moving with a speed of 2.2 m/s‚ what is the kinetic energy of the entire system? KETOT = KEwheel+KEweight = (1/2)(I)(w2)+(1/2)(m*v2) =(0.5* v2)(m+1/2M) =0.5*(2.2^2)*(3+(.5*15)) J b) If the system started from rest‚ how far has the weight fallen?

    Household energy consumption is examined in the specific context of home heating expenditures. Analysis of home heat costs across stages of the family life cycle reveals a distinctly different pattern than previously found when total household energy costs were examined. In contrast to the curvilinear pattern where expenditures peak during middle stages of the life cycle‚ these data show a positive linear relationship where higher costs are associated with elderly consumers. The research focus is

    swing it is momentarily stationary. It has zero kinetic energy and maximum gravitational potential energy. As the pendulum falls the potential energy is transferred to kinetic energy. The speed increases as the pendulum falls and reaches a maximum at the bottom of the swing. Here the speed and kinetic energy are a maximum‚ and the potential energy is a minimum. As the pendulum rises the kinetic energy is transferred back to potential energy. The speed of the pendulum decreases and falls to zero as
